Why is the Rebound Rating >1?

By : Ituta Darryl

GravityGravity 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.

PhysicsPhysics,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.

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.

Proven Fact

people say all potential energy is converted to kinetic energy.

That is not true this is why.

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.

SolveThink 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?

THE ANSWER NObecause it hasn't completely fallen in this case.

Kinetic Energy

watch

Potential Energy

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 present.\

Conclusion

So 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.

Thank youthank you all for paying attention
