if the tennis ball is stationary the energy in it is its gravitational energy given by the formula MGH=E where H is height in m M is mass of tennis ball in kg and G is 9.8 meters per second squared. if the ball is moving however the formula for energy from velocity is 1/2MV2=E ware M is mass in kg and V is velocity in meters per second
kinetic energy
tennis ball
A tennis ball, when impacted, dissipates about 45% of the energy applied to it. This means that it only absorbs and returns 55% of that energy. That is why in the test standard for tennis balls, dropping it from 100 inches, it only rebounds 53 to 58 inches. It is returning that much energy. The strings of the racket, however, return 90% of the energy they are impacted with. So, when the tennis ball hits the strings and they stretch (absorb the energy), they will return 90% of that force in the return of the ball. When a ball hits strings with a higher tension, the force is exerted on the ball, instead of the strings, and the energy return is closer to the 55% range.
A moving tennis ball (or a moving object of any type) has kinetic energy, the enery of motion. Some of this energy gets converted into heat, when the ball bounces, and the ball therefore gets warm. The ball is moving less, but the kinetic energy has not disappeared, it has just changed into another form of energy.
Rolling (motion) is an example of Kinetic Energy.
Kinetic energy is energy in motion. So, there is kinetic energy when the ball is moving through the air. There is sciatic energy when the ball is resting on the racket! Hope this helps.
When you throw the tennis ball, it flies for a distance before dropping down because when you throw the tennis ball, you use force, which is transferred to the tennis ball, which then converts to kinetic energy (movement energy), to allow the tennis ball to go far.
freeze it... the cold slows down the cinetic energy in the ball
Because the hard surface doesn't absorb any of the energy of the tennis ball - thus the ball bounces higher than if it was dropped on a softer surface.
