Because when it falls with a speed of let's say 10 mph, It hits the ground, and upon impact the ground takes the kinetic force/momentum/scientific thingamabob and returns it with the same force, and that causes the ball to bounce back. Like if you hit your head off a wall, it hurts because the wall bounces back the force that you hit your head off with back to your head.

When a golf ball is dropped to the pavement it bounces back up?
When a golf ball is dropped onto the pavement, it compresses upon impact and stores some of the energy. This stored energy is then released, causing the ball to bounce back up into the air. The elasticity of the ball and the pavement's surface play a role in dictating the height and speed of the bounce.
Why does a ball spin the opposite direction after it hits the ground?
ANSWER it has to do with the way the ball is launched. if theres a topspin on the ball, when the ball hits the ground, it will pick up speed on contact. if it is spinning back toward you, upon contact with the ground, it will most likely bounce back at you. did i help any?
Will a ball of glass bounce higher then a ball of rubber?
Yes it will. Although both balls will have the same amount of energy when they hit the ground, energy is spent trying to reform the rubber ball. The glass ball does not get deformed on contact and so it has more energy to bounce higher.The resonance of glass is higher and creates more energy from the normal force pushing back up on the glass from the ground. This also has to do with the fact that a crack in glass travels hundreds of miles per hour. See Justinsearch below for other crazy facts.I have serious doubts concerning the above. The only way a glass ball will bounce is if it falls upon a surface with some degree of elasticity. It would be the elasticity of the surface that would then propel the ball upwards. A glass ball falling any appreciable distance onto a solid granite slab will shatter, not bounce. The shatter is the result of the energy the above contributor says will make the ball bounce higher. Possibly, a ball made of extremely strong tempered glass may not shatter, depending on several factors. In such a case, the energy upon impact would crack the surface, or be absorbed by the ball and surface in the form of heat; some would be converted into noise. The reforming of the rubber ball is the very thing that propels the rubber ball upwards. If a ball were perfectly elastic, it would absorb a certain amount of energy on impact, and then it would expend all of that energy in the process of 'reforming'. A perfectly elastic ball would do this indefinitely, if you could eliminate all possible transfers of energy in the form of friction and other exotic effects. What we observe in the real world is that a rubber ball will bounce less high at each bounce because of the inevitable absorption of energy as it continues. When the ball comes to rest, it will have expended the same amount of energy that it had in potential form at the moment it was dropped. This would include some degree of heat that the ball inevitably absorbs. The energy in the glass ball is expended in the process of shattering the ball, and/or noise, heat, cracking of the surface, etc.Above are some very true points. The idea is easier to see for most when you think of a glass ball of small proportions. A small glass ball will bounce higher than a small rubber ball, and if small enough it would not crack even on a granite slab from a great height. If the ball is to be larger and heavier yes it would need to be of a "extremely strong tempered glass". "The reforming of the rubber ball is the thing that propels the rubber ball upwards" yes exactly, from the normal force of the ground. However the more reforming that is needed, the more energy is lost, for example a flat ball.
When does a bowling ball have potential energy?
A bouncing ball has the most potential energy when it is at the top portion of its bounce. Technically... A bouncy ball is at it's max. potential energy when it's still in your hand, but if you mean after it's been thrown, it's when it's at the highest point of that particular bounce.
How does force act upon a falling feather?
Gravity is working to pull the falling feather down to the ground.
Why does a ball bounce upon falling?
because it is round

What do you do when life does not go your way?
Realize that if there is anything that is steadfast and unchanging, it is change itself. Learn from the experience and build upon it. It's like throwing down a rubber ball. It will always bounce back. It may not bounce back in the same direction, but it will always bounce back. When the direction changes, look at it as an opportunity to learn from and build on. Your attitude will have a lot to do with moving forward even when the direction changes, and moving forward in a positive way. Attitude is everything!
What factors affect the bounce of a dropped ball?
The factors that affect the bounce of a dropped ball include...... the height from which it is dropped; the force applied to it, if any, when dropped; the acceleration of gravity, which is different depending upon what planet you're on ; the elasticity of the ball; the density of the atmosphere, which affects "air resistance"; and the rigidity and elasticity of the surface on which the ball bounces.
What makes a ball bounce higher?
A ball bounces because it's shape changes when it hits another object, then it returns to it's original form, pushing itself away from the object. When a ball is cold it's molecules don't move as much, so the shape changes less when it hits an object.
What happens to a tennis ball during impact?
According to the USC website (refer to the link, below): "The three components in the system of ball-racket interaction are the ball, the racket frame, and the strings. During impact, all three components deform to some degree; such deformation is caused by the energy transferred amongst the three components. The ball carries kinetic energy and transfers some of it to the racket frame and strings upon impact. Some of this transferred energy is given back to the ball, allowing the ball to bounce back."
Does the mass of the ball affect how high it bounces?
a ball can never bounce over the height from which it was bounced unless u aplly a force. The factors that affect the bounce of a dropped ball include the height from which it is dropped; the force applied to it, if any, when dropped; the acceleration of gravity, which is different depending upon what planet you're one; the elasticity of the ball; the density of the atmosphere, which affects "air resistance"; and the rigidity and elasticity of the surface on which the ball bounces. weight also affect the bounce height.
Does temperature affect the bounce of a rubber ball?
Temperature does not affect the bounce of a rubber ball. Let's say you bounce a rubber ball on the grass. The result will be different then bouncing a rubber ball on a concrete surface. The result is different because you are using a solid, hard surface to bounce the ball with. But the temperature will not affect the bounce of a rubber ball. you can test it out for youself.
What factors affect a bouncy ball from bouncy?

If a ball is perfectly elastic and is dropped in a perfect vacuum will gravity ALONE be enough to make the ball bounce lower with each successive bounce finally coming to rest?
The answer is no. Perfect elasticity means the ball does not lose energy to internal heating. We presume the surface dropped upon is also perfectly elastic. Vacuum means the ball has no air resistance thus no drag. An argument could be made that the bounce must not make any sound, since this would remove energy from the system. There are some other odd mechanisms one could think of, like van der Waals, but the basic answer you are looking for is "no".
