Unity’s physics system lets you handle 2D physics to make use of optimizations available with 2D. You can use the following physics 2D components with Unity:
| Topic | Description |
|---|---|
| Rigidbody 2D | Learn how RigidbodyA component that allows a GameObject to be affected by simulated gravity and other forces. More info See in Glossary 2D works. |
| Collider 2D | Understand the types of ColliderAn invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh - a rough approximation is often more efficient and indistinguishable in gameplay. More info See in Glossary 2D components available to use with Rigidbody 2D. |
| Physics Material 2DUse to adjust the friction and bounce that occurs between 2D physics objects when they collide Physics Material 2DUse to adjust the friction and bounce that occurs between 2D physics objects when they collide More info See in Glossary |
Control the friction and bounce between colliding 2D physics objects. |
| 2D Joints | Understand the types of 2D JointsA physics component allowing a dynamic connection between Rigidbody components, usually allowing some degree of movement such as a hinge. More info See in Glossary available to use with 2D GameObjectsThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it.

| Constant Force 2D | Add constant forcesA simple component for adding a constant force or torque to game objects with a Rigidbody. More info See in Glossary to a Rigidbody 2D. |
| Effectors 2D | Direct the forces of physics when GameObject colliders are in contact. |
