# Physics Material 2D reference

> Explore the properties that control the friction and bounce between colliding 2D physics objects.

Use a **Physics Material 2D** to adjust the friction and bounce that occur between 2D physics objects when they collide.

For more information on game physics, refer to [3D Physics](/engine/6000.0/manual/physics-section.md).

## Use a Physics Material 2D

To create a Physics Material 2D, go to **Assets** > **Create** > **2D** > **Physics Material 2D**.

To use your Physics Material 2D, assign it to the **Material** property of a [Collider 2D](/engine/6000.0/manual/unity2d/2d-physics/collider-2d.md) or [Rigidbody 2D](/engine/6000.0/manual/unity2d/2d-physics/rigidbody-2d.md) component.

## Properties

A Physics Material 2D contains the following properties.

| **Property**         | **Description**                                                                                                                                                                                                                                                                                                                  |
| -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Friction**         | Sets the coefficient of friction for this collider.                                                                                                                                                                                                                                                                              |
| **Bounciness**       | Sets the degree to which collisions rebound from the surface. A value of 0 indicates no bounce while a value of 1 indicates a perfect bounce with no loss of energy.                                                                                                                                                             |
| **Friction Combine** | Defines how to combine both material friction values when two colliders interact. The options are:**Average**: Uses the average of the two values.**Mean** (Default): Uses the mean of the two values.**Multiply**: Multiplies the two values together.**Minimum**: Uses the smaller value.**Maximum**: Uses the larger value.   |
| **Bounce Combine**   | Defines how to combine both material bounciness values when two colliders interact. The options are:**Average**: Uses the average of the two values.**Mean**: Uses the mean of the two values.**Multiply**: Multiplies the two values together.**Minimum**: Uses the smaller value.**Maximum** (Default): Uses the larger value. |
