# Constant Force component reference

> Reference page for the Constant Force component.

**Constant Force** adds constant forces to a [Rigidbody](/engine/6000.3/manual/physics-section/physics-overview/rigidbody.md). This is useful for GameObject movement that accelerates over time.

If you add a Constant Force component to a GameObject that does not have a Rigidbody, Unity automatically creates and adds a Rigidbody to the same GameObject.

For more details, see [Apply constant force to a Rigidbody](/engine/6000.3/manual/physics-section/physics-overview/rigidbody/rigidbody-constant-force.md).

## Properties

For all values, a higher value produces a stronger force, which in turn produces a faster initial velocity.

| **Property:**       | **Function:**                                                                                  |
| ------------------- | ---------------------------------------------------------------------------------------------- |
| **Force**           | Define the direction of the linear force. The XYZ vectors refer to the scene’s global axes.    |
| **Relative Force**  | Define the direction of the linear force. The XYZ vectors refer to the Rigidbody’s local axes. |
| **Torque**          | Define the global axes that the Rigidbody rotates around.                                      |
| **Relative Torque** | Define the local axes that the Rigidbody rotates around.                                       |
