### Remarks

A [Collider2D](/engine/6000.3/script-reference/unityengine/collider2d.md) can have a [PhysicsMaterial2D](/engine/6000.3/script-reference/unityengine/physicsmaterial2d.md) assigned in several ways: directly through the [Collider2D.sharedMaterial](/engine/6000.3/script-reference/unityengine/collider2d/sharedmaterial.md), indirectly through the attached [Rigidbody2D.sharedMaterial](/engine/6000.3/script-reference/unityengine/rigidbody2d/sharedmaterial.md), or by using the global default. If no [PhysicsMaterial2D](/engine/6000.3/script-reference/unityengine/physicsmaterial2d.md) is assigned, a default value is used.
