# useContactForce

> Should the impulse force but applied to the contact point?

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.Physics2DModule

```csharp
public bool useContactForce { get; set; }
```

### Remarks

When true, the force is applied to the contact point which may cause the target to rotate.  When off, the force is applied to the center-of-mass, therefore no rotation is produced.
