How does the height from which a ball is dropped affect it's bounce?
h=(mgH-x)/mgm is massg is acceleration due to gravityH is height from which it is droppedh is height to which it returnsx is the energy lost due to collission with floor(probably dependant on the coefficient of restitution)well an object falls at 9.6 meters a second so every thing falls at the same time no matter what the height is but the bounce depends on what its made of.Serena Williams (USA)Real answer: Because of gravity. The higher you drop a ball, the more force acts upon it, pulling it towards the ground. After hitting an object, an equal and opposite force acts upon the tennis ball, repelling it. This is known as Newton's 3rd law.
