| [angle](/engine/6000.0/script-reference/unityengine/jointsuspension2d/angle.md)               | The world angle (in degrees) along which the suspension will move.                              |
| [dampingRatio](/engine/6000.0/script-reference/unityengine/jointsuspension2d/dampingratio.md) | The amount by which the suspension spring force is reduced in proportion to the movement speed. |
| [frequency](/engine/6000.0/script-reference/unityengine/jointsuspension2d/frequency.md)       | The frequency at which the suspension spring oscillates.                                        |
