# Constant Force 2D reference

> Explore the properties that control constant forces applied to a Rigidbody 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.

## Properties

| **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.                                 |
