The ball's momentum changes in one direction, the momentum of planet Earth in the opposite direction.

When you bounce a ball why do the particles on the floor bounce up with it?
Conservation of momentum. When the ball bounces off the ground, the momentum of the ball is conserved, and since it bounces back up, the ground has to go down. On a hard concrete surface, which is very rigid, the ball moves a large portion of heavy concrete only a minute amount. On a wood or matted floor, only the ground right around the ball goes down (because the material is somewhat elastic/flexible). The particles either appear to jump because the ground is lowering, or they are flung upwards when the ground reverts back to its normal shape.
Why does the ball not bounce as high when its first dropped?
The answer lies in co-efficient of restitution. (COR) COR is the ratio of speeds before and after impact. Normally, it is expected that the ball should reflect off the surface with the same speed with which it strikes. However, this happens only in the case of elastic collisions. Elastic collisions are ideal collisions in which both momentum and kinetic energy are conserved. COR=1. In this case, the ball bounces as high as the height from where it was thrown. In reality however, collisions are inelastic. COR<1. K.E is not conserved. Energy is lost in other forms like heat as a result of which the ball doesn't bounce as high.

Is it illegal against you to cash a check and it bounces?
no
Why does a basketball rise to a lower point each times it bounces?
Because it loses momentum each time it bounces. That is why you use your hand to bounce the ball, giving it more momentum going down which causes it to hit the ground harder. During the spit second it hits the ground, the air pressure in the ball increases, causing it to bounce back up to your hand.
If you write a check and it bounces can they get a warrant against you?
Yes, they can get a warrant. It is a crime.

Comparison between elastic and inelastic collision?
In an elastic collision, all initial kinetic energy is fully restored as final kinetic energy. where nothing is converted into noise, heat or any other form of energy. In an inelastic collision, kinetic energy is "lost" to thermal or sound energy.
What happens to the momentum of an object when it hits the ground?
Depending on the properties of both material and surface it hits, the collision may be elastic, inelastic or anywhere in between. In either case, a portion(0 to 100%) of momentum is transferred to the ground and the rest remains in body(ie. it bounces).

A ball rolls down a hill and hits a box the momentum of the ball decreases what happens to its momentum?
Momentum (as energy) isn't lost, it is transferred. Momentum is lost to friction when the ball is rolling, but in the described situation, the momentum is basically all transferred to the box upon impact. The box may tip over if light enough, or the box may break, or if heavy enough and built well enough, the box may absorb the impact and be left seemingly untouched. If the ball continues to roll after impact (if it bounces over/around/off of the box, then only partial momentum has been transferred to the box.
