In Unity, a Physics Material 2D is used to adjust the friction and bounciness that occurs between 2D physical objects when they collide. This can be useful for a range of different scenarios, for example:

• Making icy ground or platforms slippery

• Making ground or platforms less slippery, or preventing an object from sliding

• Making an object bouncier (such as a ball)

• Making an object less bouncy

• and many other uses
