# linearDrag

> A force applied to slow linear movement of any Collider2D in contact with the effector.

## Definition

* **Type:** Property

* **Assembly:** UnityEngine.Physics2DModule

```csharp
public float linearDrag { get; set; }
```

### Remarks

Linear drag provides the ability to slow [Collider2D](/engine/6000.0/script-reference/unityengine/collider2d.md) in contact with the effector.  Increasing the linear drag simulates an increasingly viscous fluid making it harder for colliders to move through it.

It is similar to ::Rigidbody2D::drag but is more complex in that drag is applied not only as a function of velocity but also takes into account the [Collider2D](/engine/6000.0/script-reference/unityengine/collider2d.md) submerged area.  The drag force is applied to the center of the submerged area and therefore can generate torque i.e. make the object rotate.
