Why is the Rebound Rating >1?

Gravity
Gravity is a force which attracts the objects to the ground.
Thats why we're talking about a basketball or a tennis ball or any other sports balls.
All starts with gravity and physics first gravity.
Gravity is essential for sport balls because if there wasn't any they wouldn't touch the ground fast once more.
Gravity keeps the ball intact with the ground.
without gravity some sports wouldn't exist.Slide3
Physics
Physics,the law of physics based on behavior and observation.
Physics it brings us to the subject on potential energy.
Potential energy
is the ability of a system to do work due to its position or internal structure.
Basketballs bounce, do to kinetic energy but not all potential energy is converted to kinetic energy headache yet.Slide4
Kinetic energy
kinetic energy is a form of energy formed by its movement example roller coasters it moves theres kinetic energy.
Anything that moves has kinetic energy did you know a rail brings a roller coaster up and once it lets it go its gone by it self with the kinetic energy.Slide5
Proven Fact
people say all potential energy is converted to kinetic energy.
That is not true this is
why
.Slide6
Why?
An object is moving in the sky will have kinetic energy and potential at the same time.
Like i said potential energy is an energy that hasn't been released yet.
If you dribble a ball 100 times the rating would be 1 because of the energy as more you dribble the more the energy it gets in the ball which is
why the rating is 1.
this rating could multiply by each 100 rebound.
In a case of a basketball.Slide7
Solve
Think of a ball 1 mile up in the air begins to fall. After it falls 10 feet, it releases some but not all of its potential energy, it has built up some kenetic energy as well from the motion of falling 10 feet, but still has 5270 feet worth of potential energy to go. What happens as the ball falls does it gradually changes all of its potential energy into kinetic energy?Slide8
THE ANSWER
NO
because it hasn't completely fallen in this case.
Kinetic Energy
watch
Potential EnergySlide9
Experiment
Ok,I will dribble this basketball once 100 times to prove the vibration will mean the potential energy is in the ball and hold this other ball to see the difference if it is ill tell you why.
And my partner will try it and see if he feels the difference is pre
sent.\Slide10
ConclusionSo i've proven that kinetic energy can be present at the same time as potential energy because you could feel the potential energy while it was moving. Slide11
Thank you
thank you all for paying attentionSlide12
