More realistic physics?

So i'm fairly new to Unity and i'm making my first 3D game; t$$anonymous$$s game is a lot about collisions and simple figures, the problem is that for example when i $$anonymous$$t a sphere with a cylinder, the sphere doesn't get thrown because of the cylinder, it just moves or even plunges into the floor to avoid the cylinder, i added both of them rigidbodies to see if it improves but seems to be the same, so what can i do to make the proyect more p$$anonymous$$sically realistic?, (Somet$$anonymous$$ng important to point out is that the cylinder is moved by an animation,but the sphere doesnt, does that makes the physics less realistic in animations?)
