Physic Material is used to give an object physical property like impact and friction. (like bounce when hit)
| Property | Feature | 
|---|---|
| Dynamic Friction |  The friction applied to moving object. Basically, use a value between 0 and 1. Smaller the value, slippery the object will be, higher the value, sticky the object will be.  | 
	
| Static Friction |  The friction applied to an object resting on a surface. Higher the value, the more power is required to move the object.  | 
	
| Bounciness |  The elasticity of the surface. Higher the value, lesser the energy lost when the object bounces. The value of 1 means, the object bounces without losing any energy.  | 
	
| Friction Combine | How to process the friction between colliding objects. | 
| Average | The two friction forces are averaged. | 
| Minimum | Smaller of the two friction forces is used. | 
| Maximum | Higher of the two friction forces is used. | 
| Multiply | The two friction forces are multiplied with each other. | 
| Bounce Combine |  How to process the bounciness between colliding objects. The same as the FrictionCombine.  |
