- Constant Force 2D

**Constant Force 2D** is a quick utility for adding constant forces to a **Rigidbody 2D**. This works well for one-shot objects like rockets, if you want them to accelerate over time rather than starting with a large velocity.

Constant Force 2D applies both linear and torque (angular) forces continuously to the Rigidbody 2D, each time the physics engine updates at runtime.

Property: |
Function: |
---|---|

Force |
The linear force applied to the Rigidbody 2D at each physics update. |

Relative Force |
The linear force, relative to the Rigidbody 2D coordinate system, applied each physics update. |

Torque |
The torque applied to the Rigidbody 2D at each physics update. |
