The sweet spot 3. Batand ball collisions The collision of a bat and a ball can be understood bytreating the bat as a heavy ball whose mass depends on the impact point. Thewhole mass of the bat is not involved in the collision, unless the collisionhappens to occur at the centre of mass of the bat. Otherwise, the effectivemass of the bat is less than its whole mass. To understand such collisions itis important to first understand the physics of a collision between one balland another.

Investigating the physics of impact necessarily involves examining the literature of mainstream sports which have something in common with croquet: The point of interface between the player and the game is an implement striking a ball. It should come as no surprise that the golfing literature is full of studies on this subject, giving rise to countless golf club innovations; most of them short-lived fads. But some of the scientific observations have been effectively incorporated in golf club design - and in croquet mallets as well.

When we breathe, we extract oxygen from the air, and use that oxygen for metabolism , which is how we convert the food we eat into useable energy to do the things that we do. One of the by-products of metabolism is carbon dioxide ; whenever we exhale, we are getting rid of the carbon dioxide that our bodies produce. The main purpose of breathing, therefore, is to provide our bodies with oxygen, and rid our bodies of carbon dioxide. We humans are terrestrial (land-dwelling) mammals, and as such, our lungs are designed to breathe gas. Unlike fishes, we have no gills, so we cannot breathe water. Therefore, the first problem we must overcome to explore the underwater realm is Read More Go to Site Exploratorium: Sport Science Votes:0 What's the science behind a home run?

In the early days of golf the balls were smooth. Players noticed that as balls became old and scarred, they traveled farther. After a while players would take new balls and intentionally pit them. 1 Eventually manufacturers caught on and supplied balls with dimples. "Some manufacturers even claim that the shape of the dimples is significant; one states that polygonal dimples are superior to round ones!" 2 In any case, the superiority of dimpled golf balls is well established: modern experiments sho Read More Go to Site It's all about Speed: The Physics of Luge Votes:0 It's all about Speed: The Physics of Luge We all know what it feels like to travel 65 miles an hour sitting comfortably in a car.

If a ball impacts at either of these spots, the force transmitted to the hand is sufficiently small that the player is almost unaware that the impact has occurred. If the ball impacts at a point well away from the sweet spots, the impact can be quite painful. One of the sweet spots is the vibration node, located near the centre of the strings. The other sweet spot is called the centre of percussion (COP). These and some other significant spots on a racquet are shown in Fig. 1. Fig 1: Racquet Spots Contrary to popular opinion, the two sweet spots do not coincide with the point at which the ball rebounds with maximum speed, nor do they define the spots where the force on the hand is ze Read More Go to Site Measurement in sport-Box 3 Votes:0 Published by Australian Academy of Science Measurement in sport – the long and the short of it Box 3 | Physics in sport: Forces on an athlete A force can be defined as a push or a pull. When running or walking we use the energy in our leg muscles to push backwards on the ground with one foot while the other foot is moving forward. Forces always come in pairs called action-reaction pairs. So, when we push backwards on the ground, the ground also pushes forward on us. Sir Isaac Newton first proposed this idea in the 1600s. He said that for every force (action) there is an equal force (reaction), which acts in the opposite direction. Action-reaction pairs of forces associated with an athlete are due to gravity, friction with the ground and air resistance. Ground reaction force and shock Read More Go to Site PBS | About This Site . Retired Site Votes:0 Friday, November 23, 2007 by topic...

What does bowling have to do with Newton's 1st law? If you have ever bowled, you know that after rolling the ball it continues to move across the alley until it comes into contact with the pins. After being put into motion, the bowling ball will remain in motion until friction eventually slows it down.

Fleming/Chronicle Staff What happens when the club hits the ball? A look at the physics of golf could reveal some clues to improving your game. A golfer's swing is an example of torque - using force to create rotation. The golfer twists his hips and his shoulders to swing the club. The energy he exerts is transferred to the clubhead, which propels the golf ball when the two collide. Take flight with the physics of the golf ball.

Introduction An understanding of how a gymnast twists in the air is still not complete, even in the mind of physicists and mathematicians; however, the past decade has seen much progress in identifying which of these mechanisms are most effective or contributory to successful twisting. A major problem has been that, although the human body must obey the laws of physics, it does not act as a rigid system and therefore is not easily analyzed. In fact, a recent survey (Frohlich, 1979) of the 59 physicists who responded to a questionnaire, mor Read More Go to Site von Neumann stability analysis Votes:0 Next: The Crank-Nicholson scheme Up: The diffusion equation Previous: An example 1-d solution von Neumann stability analysis Clearly, our simple finite difference algorithm for solving the 1-d diffusion equation is subject to a numerical instability under certain circumstances. Let us try to establish when this instability occurs. Consider the time evolution of a single Fourier mode of wave-number : (204) Substitution of the above expression into our finite difference scheme ( 197 ) yields (205) or (206) where (207) Thus, the amplitude of the Fourier mode is amplified by a factor at each time-step. In order for the differencing scheme to be stable, the modulus of this amplification factor must be less than unity for all possible values of .
