In real-world physics, objects that can collide have different surface textures and properties that affect how they collide with each other, and how they interact with each other.
To control how objects collide with each other in the physics simulation, you can adjust the friction and bounciness of your colliders. In Unity, you use the Physic Material asset to control these parameters. The Physic Material asset is represented in the API by the PhysicMaterial class.
For more detailed information on how PhysX applies friction and bounce, see the Nvidia PhysX documentation Rigid Body Dynamics: Friction and Restitution.
