Check out Sniper Skin's easy to install, weatherproof and dural bat grips here! Thats the sport that demands the most from the athletes who compete in it. . What is velocity of bullet in the barrel? Reflexes. Sara Chodosh The node sweet spot differs from the center of percussion sweet spot. In theory, this should mean that a homerun hit right on the sweet spot would sound different from an off-target pop fly. Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. The results are very surprising. 29 0 obj At some point you will feel almost no vibration when you tap. A knob and end loaded bat may weigh the same, for instance, but the end loaded bat will have a higher MOI. We offer our conclusions in Section 6. Here you'll find information on the game of baseball, from the rules to the history. << The illumination of the ordinaryof why the sky is blue or why the stars shineis not the least important role of physics and physicists. When a ball player hits the ball with the bat, it produces an enormous amount of force on the bat in a split second - the impact could mean up to 5,000 lbs of force. But its not that simple. . Movies showing the collision of a baseball with a cricket ball and the collision of two billiard balls are shown in the page on collisions. Baseball players were known to carve or whisk their own bats from various hardwoods during the early days of amateur baseball. 22 0 obj The following three movies show a batter swinging three different bats as fast as possible, filmed at 25 frames/sec. On average, the sweet spot occurs between 5 and 7 in (12.7 and 17.8 cm) from the barrel end of the bat. /N 21 0 R When a baseball player hits a ball, it generates enormous amounts of energy. Theres one where it feels good in your hands, one where the ball comes off the fastest. When it comes to the distance traveled by a ball, speed and speed at which it sails off the bat are all important factors. Where is the center of mass in a baseball bat? Yes, every ounce makes a difference. We use the idea that if a body collides with something, then its angular momentum is conserved with respect to the point of impact. Other research indicates that the 'sweet spot' lies between the nodes of the lowest 2 vibrations of the bat. The batter might find that he needs to change the way he swings the bat if the swing weight is altered, or he might have a grooved swing technique and swing every bat the same way. /R [52 73 308 791 ] << The sweet spot of a baseball bat Rod Cross Physics Department, University of Sydney, Sydney 2006, Australia Received 10 November 1997; accepted 22 January 1998 The sweet spot of a baseball bat, like that of a tennis racket, can be dened either in terms of a vibration node or a centre of percussion.In order to determine how each of the sweet spots inuences the ''feel'' of the . It would therefore not be surprising if a softball can be pitched at say 1000 rpm. << << If you hit . To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. 2 0 obj At one point, called the node, the waves always cancel each other out. << /V 22 0 R The experiment can be done at low bat and ball speeds since the essential physics of the problem does not depend on the actual bat and ball speeds. Also shown for comparison is a bounce off a heavy block of granite so that the COR of the ball can be determined. It was found, by measuring the frequencies of lots of aluminum tubes (see photo) that the frequency is directly proportional to the wall thickness and inversely proportional to the tube diameter squared. While the center of mass moves one way (nearly upward here), the handle moves the opposite way (nearly downward). endobj Every sport is governed by the laws of science physics, aerodynamics, kinematics, etc. Preliminary In order to indicate the origin of the baseball bats problem, the following preliminary are worth mentioning. Mass has no effect on distance, but if you cant generate enough bat speed to overcome mass, you are doing yourself no favors and going backwards. The bounce was filmed at 300 fps and is played back at 30 fps in slow motion. Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists. My particular research interests are two-fold: the physics of the baseball-bat collision and the flight of the baseball. Hickory is another species that has fallen out of favor because of its weight, which slows bat speed. By understanding the physics of baseball bats, players can maximize their performance on the field. Why? The spot is close to the centre of percussion (COP) for a freely supported bat, so it was thought at one time that the sweet spot might be associated with the COP. Ash bats, on the other hand, are more flexible, making them perfect for contact hitters. Choosing the right wood is essential for the proper performance of baseball bats. The following three movies show a batter swinging three different bats as fast as possible, filmed at 25 frames/sec. How much force does a baseball bat generate? The pain of hitting away from the sweet spot motivates you to learn how to find itthat, or buy a composite bat with a vibration damper in the handle. Their sweet spots are anywhere between 10.16 and 25.4 cm from the barrel end. /V 9 0 R Wood bats hit farther than metal bats, which is the clear distinction between them. For further details, see American Journal of Physics, September 1998 and also American Journal of Physics, 69, 231-232 (2001). I havent listened to different recordings of hits to see if theres a noticeable difference, says Russell. That is, a large fraction of the stored elastic energy in the wall is retained as vibrational energy in the bat. George has always been passionate about physics and its ability to explain the fundamental workings of the universe. You can find the sweet spot by gripping the bat handle with one hand in the same place as when youre swinging. The swing weight of the bat (that is, its moment of inertia) can be determined from the measured period of oscillation when swung as a pendulum. Last . /Title (Untitled) The weight and construction of a bat also affects the bounce factor q, and it affects the time and position of the bat at which the swing speed is a maximum. << 2) Choose the right turn model As discussed earlier, a wider handle will improve bat durability and reduce the likelihood of breakage. The same thing happens when swinging a golf club, but it is not a well-known effect. So, why does the MLB still use wooden bats? Both papers can be downloaded here and here. This is the online home for all things baseball. I have done quite a bit of independent research in both areas. The above results are more or less as expected, in that light bats can be swung faster than heavy bats. I tossed a 12 inch softball at very low speed and filmed the result, using two hands instead of one to increase the spin rate and to make sure the spin axis was horizontal. In any collision, energy from both objects gets transferred around, but in a swing your goal is to put as much energy as possible back into the baseball. It was found, by measuring the frequencies of lots of aluminum tubes (see photo). Curve Balls Sweet Spot / Corked Bats / Questec-MLB Zone Evaluation. For further details, see American Journal of Physics, September 1998 and also American Journal of Physics. An example of data being processed may be a unique identifier stored in a cookie. Pitching Mechanics.- 6. /N 7 0 R We call the point where a baseball bat has its nodes the sweet spot. Popular Science 71.6K subscribers Subscribe 162 19K views 4 years ago Where is the sweet spot on a baseball bat and how do you find it? | An aluminum bat is much lighter than a wooden bat, increasing its range and allowing it to hit the ball farther. Because of the weight distribution, drop 8 bats tend to have a higher weight per foot than standard 8 bats. In bats made of maple wood, like the Axe Bat, it's easy to find the strongest grain. In theory, the ball bounces best for an impact at the center of mass of the bat, provided we can ignore bat vibrations. Share your thoughts with us below! /R [316 73 572 791 ] When a wake is pushed down, a fastball is pushed up. Current research on the physics and science behind the game of cricket centers on the performance of the batsmen and bowlers. The fundamental mode of a wood bat has a node located typically about 17 cm from each end and a frequency typically of about 170 Hz. Initially, the force on the handle is in the opposite direction to the motion of the handle. When To Know Its Time To Replace Your Baseball Mitt, Customizing Your Baseball Bag: A Guide To Personalizing Your Equipment. Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. Recent Research Highlights. The ball also generates potential energy through the bat, resulting in a powerful, far-reaching hit. The bat was swung through an axis 143 mm from the knob end. For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. Ball exit speed = (1 + q)V where V = bat speed at impact point just before the impact. So, for the sake of the integrity of the game and safety, bats have remained wooden. >> As a result of the transfer of kinetic energy from the bat to the ball, it has increased mass and kinetic energy. The heavier the bat, the higher the bats bat speed. The spot is close to the centre of percussion (COP) for a freely supported bat, so it was thought at one time that the sweet spot might be associated with the COP. As a smaller player, you will generally be able to achieve faster bat speeds with a lighter bat. Hitting on the sweet spot ensures you dont lose any more energy to making vibrations inside the bat. The sound made by a bat can be described as a "ping". /P 20 0 R << The experiment described below would be an ideal project on the physics of baseball, for any high school or University physics student. Sniper Skin carries a line of great bat grips which are easy to install and remove while virtually eliminating the sticky gunk left on your bat. But how does a batter do it? The result: a harder-hit ball. Baseball bats (typically aluminum) are made up of either hardwood or metal. You can tell the bat is too heavy if the player appears to be chopping at the ball. These modes are shown in the diagram above. This force is required to change a 5 1/8th-ounce ball from a speed of 90 mph to a speed of 110 mph, this distorts the baseball to half its original diameter and the bat is compressed one fiftieth of its size.. Results for a baseball dropped from heights of 1, 5, 10 and 15 cm onto a piezo are shown below. Where is the sweet spot on a bat? Nathan hopes to test the theory of Robert Adair, a Yale University physics professor and baseball guru, who believes the subjective sweet spot sits on the node where the bat's lowest frequency vibrations drop out. /V 12 0 R /N 12 0 R A pitch produces a turbulent wake of air behind the ball. If this is the case, the bats likely too heavy if it cant keep its grip in place for at least 20 seconds. The cookies is used to store the user consent for the cookies in the category "Necessary". When a bat is made out of a hard material, it allows the bat to transfer more energy to the ball when it is hit, enabling the ball to move faster and farther. Joe Jackson, a shoeless man, would prefer a custom-built bat known as Black Betsy. The shapes of the force vs time curves are interesting since they tell us how the force on the ball varies with the amount of compression. /N 22 0 R Similar results are obtained at much higher ball speeds, the forces and x values being correspondingly much larger. /P 11 0 R window.mc4wp = window.mc4wp || { stream 9 0 obj /R [316 74 572 585 ] endobj Learn How To Personalize Your Hat With Vinyl Stickers! A lot has been learned over the years but more experiments need to be done to better understand how the ball bounces and how much spin it acquires when it bounces. Manage Settings Baseball is based on the principles of Newtons laws of motion. This cookie is set by GDPR Cookie Consent plugin. When you hit the sweet spot, the bat feels the best in your hand. A simple introduction to the physics of the collision problem is given here. A high performance bat has a strong trampoline effect and hence a relatively large COR. endobj There is a significant difference between end-load and balanced softball bats in terms of weight distribution. Despite the old timey aesthetic to wooden bats and sweet spots, scientists actually didnt know much of anything about the acoustics (yes, acoustics) of a bat until the 1980s and 90s. This cookie is set by GDPR Cookie Consent plugin. The best wood for the Louisville Slugger bats to eat is northern white ash or maple, but wood from New York and parts of Pennsylvania can also be found. The sweet spot (where you want to hit the ball consistently) is located about 2 in from the end of the barrel to about 6-7 in on an adult bat. And we end up with 12.6 meters per second , Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, to more than 1,200 m/s (3,900 ft/s) in modern rifles with high-velocity cartridges such as the , Summary. /P 14 0 R /Width 77 The length, weight, and shape of the bat also affect its performance, as longer bats tend to have more power, and heavier bats tend to have more control. 9-d\DA=cZ0Q>gIM$$;cd2O@&a;X,Nn_aP(]I1aRc(K1^ue> /BitsPerComponent 8 16 0 obj How do you control where to hit a baseball? /V 18 0 R The second you swing one, there is a certain romance to it. The ratio of ball speeds after and before colliding with the bat is called the is combined with the kinematic properties of the bat (determined from the moment-of-inertia of the bat and the impact location) to obtain the Bat-Ball Coefficient-of-Restitution, or BBCOR for the collosion. That should sound like more of a thud, because youre not hearing the vibrations inside the wood. It has been found that the swing speed for any given batter is proportional to 1/(Swing weight)^n where n is typically about 0.27 for most batters. What is the biggest problem with wind turbines? Although playing a game of cricket requires a significant amount of time, it is filled with powerful and fast forces. See, the trouble with wood is that it vibrates. ); The player has a unique preference for wood bats, which is why it is so important to select one. When he's not busy exploring the mysteries of the universe, George enjoys hiking and spending time with his family. It is almost as easy as walking. forms: { How do you find the acceleration of a system? /V 10 0 R This is not an easy rating to obtain. You can test your childs grip by having him or her hold the bat straight out in front of them, parallel to the ground, with their dominant hand. /I << 1 0 obj The ball is spinning clockwise before it bounces and hits the granite block with backspin. @L`YKUJNGBP\poR=_;Dl'P(T << The three elements of a game of baseball are critical, and the game is built around Newtons laws of motion. 24 0 obj /P 26 0 R A baseball bat is shaped in such a way to have a "sweet spot." The sweet spot is due to the fact that the CP and the VN coincide. Near the end of the swing, the batter needs to exert a large negative couple on the bat, otherwise the bat will swing around too fast and strike the ball when it is aligned at the wrong angle. The ball rotated more than 1/4 but less than 1/2 of one revolution from one frame to the next, each frame being 0.04 sec apart. I simply wanted to know whether a hand launched ball spins at around 100 rpm or whether it could be as high as 1000 rpm. It is almost as easy as walking. When a batter hits a ball, the bat will rebound from the force of the collision. /N 18 0 R 2 5 8 on a bat simply refers to the weight of the bat in ounces. Hitting the "sweet spot" is something that baseball players strive for. How is this described in Mechanics? So. Take a hammer in the other hand and gently tap the bat at various places along its length. Elastic behaviour in the horizontal direction can be described by a tangential coefficient of restitution, which is about 0.5 or 0.6 for a superball but only about 0.2 for a baseball on a rigid surface. The ideal is the 110 turn model. The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. Those two are usually close, but theyre not exactly the same. The various supposed sweet spots effectively add up to a sweet zone, about two inches wide, right on the meat of the bat. If the ball is struck at the sweet spot of the bat, then . The force of the swing is also a key factor in the performance of a baseball bat, as a hard swing can generate more power, while a softer swing can produce more control. There is no set formula. There is enough physics in it to keep a PhD student busy for a few years, but it could also be done by any high school student as a simple introduction to the physics of baseball. The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. The COR for a collision between the bat and the ball is less than 0.59 when energy is lost to vibrations, but can be greater than 0.59 if the bat has a trampoline effect on the ball. The Physics of Baseball. [/CalRGB The faster the hit ball travels, the longer it should travel. Step up to the batters box and get warmed up for the physics of baseball bats with this, You can get into the real nitty gritty of the science of MOI including complex equations by clicking through to the complete, If you have two bats, each with the same weight the bat that carries more weight in the end will perform better in terms of speed. Its center of mass is 52.6 cm from the knob end. What are the physics of hitting a baseball? The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. Wind farms have different impacts on the environment compared to conventional power plants, but similar concerns exist over both the noise produced by the turbine blades and the . Both papers can be downloaded. The impact on a baseball bat is shorter (since the bat and ball are harder or stiffer), about 1 msec. Registration on or use of this site constitutes acceptance of our Terms of Service. 10 0 obj Alan Nathan has the world's best Physics of Baseball site at http://go.illinois.edu/physicsofbaseball, Another very interesting Physics of Baseball and Softball site is maintained by Dan Russell at http://www.kettering.edu/~drussell. So grab your bat and lets dive into the science behind the swing! Players tend to feel a zing in their hands; often called bat sting. >> The first is where the bat feels best in your hands when you hit. How do you know if a bat is too heavy for a boy? This is the location of the bat that is generally regarded as the best spot for hitting the ball. The whole mass of the bat is not involved in the collision, unless the collision happens to occur at the centre of mass of the bat. hitting a baseball is either painful or frustrating. Concentration. Coefficient of Restitution = Relative speed of bat and ball after collision/ relative speed before collision, where "speed of bat" is the speed of the bat at the impact point. It does not store any personal data. In recent years, an acoustics professor and engineer, Daniel Russell, from Pennsylvania State University helped, Bat-Ball Science Mass Moment of Inertia article, The Science Behind Breaking Baseball Bats, Characterizing the performance of baseball bats, Performance versus moment of inertia of sporting implements. The node is related to where the sweet spot is - where the bat does NOT bend or vibrate. A hollow aluminum bat sounds a lot different to a solid bat since the wall of a hollow bat can vibrate in and out like a drum. Newton's third law says that for every action there is an equal and opposite reaction. If a player can maintain the same bat swing speed with a heavier bat, the heavier bat will produce higher batted ball velocity and an increase in distance. A question that is equally interesting is how the swing speed of each body segment varies as the bat speed varies and as the bat swing weight varies. The material of the bat can affect its performance, as lighter bats tend to be more responsive and have higher exit velocities. These cookies will be stored in your browser only with your consent. They can change their flight path after being exposed to different magnetic pulses, and scientists have discovered that big brown bats can adapt to these magnetic shocks. Maple and ash are the most commonly used materials in major league baseball. To increase the acceleration of the ball while it is still moving, a bat that strikes it harder will most likely accelerate faster. In case that didnt quite clear it up for you, lets break this down a bit. /R [316 73 572 791 ] The second definition is where the ball comes off the bat fastest. Maple bats are the most durable and have a larger sweet spot, making them ideal for power hitters. Each impact was recorded on a video camera at 25 frames/sec. The effect of the hands on the centre of percussion is described in American Journal of Physics, 72, 622-630 (2004). where V = bat speed at impact point just before the impact. /R [316 73 572 791 ] If you are between the ages of three and nine and weigh less than 60 pounds, you should buy a 28-inch bat if your height is between three and four inches. Physics 1998 The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. Some results for an Easton BK7 aluminum bat are shown below in 13 QuickTime movie files, each about 1 Mb. Since it's vibrations that hurt your grip, the sweet spot is clearly the point where an impacting ball doesn't cause the bat to. The same thing happens when swinging a golf club, but it is not a well-known effect. A ball takes on a different shape as it is hit because the force of the bat pushing against it is multiplied by its mass. /F 3 0 R When a batter hits a ball, the bat will rebound from the force of the collision. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. /N 10 0 R << Also,. As discussed earlier, missing the sweet spot can cause vibrations in the bat. 15 0 obj Bats and Balls.- 3. In the late 1990s, the Crisco-Greenwald Cage Study found that bats made out of materials like aluminum perform better, for a number of reasons: First of all, it takes more skill. /Length 459 What happens to the dry ice at room pressure and temperature? Licensed under CC BY-SA 2.0, via Flickr Creative Commons. The ball will rotate about 1/2 a revolution from the initial grip to the release point, in about 0.1 sec or less. When a ball is hit in the sweet spot, the collision of the bat and ball creates a compression wave which travels through the bat and is then transferred to the ball, causing it to travel further. Second, if players started using aluminum bats, every MLB record would be shattered within a year and the statistics of the game would be changed completely. Alan Nathan has the world's best Physics of Baseball site at, Another very interesting Physics of Baseball and Softball site is maintained by Dan Russell at, Lloyd Smith at Washington State University has an excellent site on the physics and engineering of softball, at. >> One question that can be answered this way is "Where on the bat does the ball bounce best?" /R [316 73 572 791 ] Baseball players obsession with bats is second nature to them. One of the definitions of the "sweet spot" is the location of the node at the barrel end of the bat. George Jackson is the founder and lead contributor of Physics Network, a popular blog dedicated to exploring the fascinating world of physics. When a very light bat is swing velocity at maximum, it has little power to transfer to the ball. Otherwise, the effective mass of the bat is less than its whole mass. One of these sweet spots relates to vibration. Cylinder 2 (500 Hz) Cylinder 3 (200 Hz), Compare sounds here (recorded with a signal generator connected to a speaker). A lot has been learned over the years but more experiments need to be done to better understand how the ball bounces and how much spin it acquires when it bounces. Boxing. The tangential COR is defined in the same way as the normal COR, but in terms of the horizontal speed of the ball at the contact point rather than the normal (ie vertical) speed of the contact point. The outgoing speed of the ball is just the sum of the two separate parts - the speed when the bat is at rest plus the speed when the ball is at rest. Hitting a ball incorrectly can make a wooden bat break due to the grain of the wood. endobj They have a hoop vibration mode - alongside the typical bending modes - that extends their sweet spots. 1 inch in length is huge. Opines that close to where the point of percussion occurs is the "sweet spot." Explains that a net force hit on small mass will go farther than large mass. Typical results are shown here for a superball, a baseball and a sorbothane ball. If the ball is also mounted as a pendulum, the experiment can also be performed in reverse, by swinging the bat at a stationary ball. If you hit a baseball somewhere other than the sweet spot, your hands will feel the vibrations. Since the CM traces out a spiral rather than a circular path, the center of the circle moves, as the bat is swung, along the path traced out by the inner circle of black dots. /Filter [/ASCII85Decode /LZWDecode ] However. The Physics of Baseball Bat Sweet-Spot. Every bat has a sweet spot.. All this means that if goal of the bats design is to provide more power and speed, it makes it more likely to to crack and shatter. Where on the bat is the ball struck with the greatest speed?
