Question

how do force act to make a rubber ball Bounce when you drop it

Answer 1

It's actually the reaction force of the floor deforming the rubber. Since rubber and most real things generate heat when deformed, the rubber never returns all the energy required to deform it, and this causes the bounce velocity to be less than the impact velocity. Look up "coefficient of restitution"

Answer 2

It is because of Newton’s law
Every reaction has equal and opposite reaction despite of that they deforming force on rubber
Rubber has natural property when you apply the external force then it’ll deform but when you remove that it’ll reform
That is the same principal when you force the rubber ball it touches on the surface it’ll deform and then it reform again while reforming the certain amount of pressure naturally applied by rubber

It all depend on the property,nature gravity, density and velocity or external force ...
