# 2D physics with the LowLevelPhysics2D API

> Create and control a 2D physics scene using the LowLevelPhysics2D API.

Create and control a 2D physics scene in a C# script using the [`LowLevelPhysics2D`](/engine/6000.3/script-reference/unityengine/lowlevelphysics2d/physicsworld.md) API.

> **Note:**
>
> This documentation is about writing C# scripts using the `LowLevelPhysics2D` API. To use 2D physics in the Unity Editor using components like the Rigidbody 2D component, refer to [2D physics](/engine/6000.3/manual/unity2d/2d-physics.md.md) instead.
