# rotationSpeed

The speed, in radians per second, at which the physics bodies are driven around the pin joint.

## Declaration

```swift
var rotationSpeed: CGFloat { get set }
```

## Discussion

Discussion The frictionTorque property limits the maximum amount of torque that can be applied to the physics bodies.
