[Unity] Physics Material

Physics Material - You can use it to change object's physical properties such as

Dynamic Friction - How much friction does the object have while moving.

Static Friction - How much power you have to give object to move it.

Bounciness - How much ratio of reaction does the object have. (0~1)

Friction/Bounciness Combine - (What if each maximum and minimum objects crush?)

Collider - The actual reacting shape of an object. If the sphere object's collider is box shaped. It moves as if it is a box. And also you can change the size and location of the collider.
