# Effectors 2D

> Approaches and techniques to working with the forces of physics when GameObject colliders are in contact.

Use Effector 2D [components](/engine/6000.7/manual/working-with-gameobjects/unity-components/using-components.md) with [Collider 2D](/engine/6000.7/manual/unity2d/2d-physics/collider-2d.md) components to direct the forces of [physics](/engine/6000.7/manual/physics-section.md) when [GameObject](/engine/6000.7/manual/working-with-gameobjects/game-objects.md) colliders come into contact with each other. You can use the following Effectors 2D components in Unity:
