# articulationBody

> The ArticulationBody of the collider that your GameObject collides with (Read Only).

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.3/script-reference/unityengine.md)
* **Assembly:** UnityEngine.PhysicsModule

```csharp
public ArticulationBody articulationBody { get; }
```

### Remarks

This returns the [ArticulationBody](/engine/6000.3/script-reference/unityengine/articulationbody.md) of the collider that your GameObject collides with. If the collider doesn't have an articulation body attached, this returns `null`.

### Examples

```csharp
using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    // Make all articulation bodies that your GameObject hits fly upwards
    void OnCollisionStay(Collision collision)
    {
        // Check if the collider your GameObject hits has an articulation body
        // Then apply the force
        if (collision.articulationBody)
        {
            collision.articulationBody.AddForce(Vector3.up * 15);
        }
    }
}
```
