because:
* the force of gravity is constant and downward * the acceleration due to gravity is therefore a result of the square of time * horizontal acceleration is zero so the horizontal velocity is constant * y=vyt -at2 x=vxt all this makes a parabola that opens downwards.
because they are made to bounce
They don't.
The balls bounce because gravity is what pulls the falling ball towards the ground! As it falls the ball gains energy from its movement
Because of gravity.
Some balls can bounce on water. It is known that all balls can float on water due to the amount of air they have inside. No, balls do not bounce on water, they may move/jump from force, but this is not really bouncing. Think of it this way, the lighter the ball the easier to move, hope that helps!
No medicine balls do not bounce unless you throw them on a trampoline.
small balls will bounce higher because they have closer particles
All Balls Don't Bounce was created in 1994.
"Any light beam moving vertically downwards in the concavity of the parabola (parallel to the axis of symmetry) will bounce off the parabola moving directly towards the focus." http://en.wikipedia.org/wiki/Parabola

because tennis balls turn in to ice when cold, and then dont bounce.
yes
To bounce...
They are hollow rubber balls. Hope this helps!
Because balls are made of rubber, and dogs are not.
They don't.
