# addAngularVelocity(_:for:)

Adds a specified angular velocity to a dynamic item.

```
func addAngularVelocity(_ velocity: CGFloat, for item: any UIDynamicItem)
```

## Parameters

`velocity`

The angular velocity, expressed in radians per second, that you want to add to the specified dynamic item. Default value is `0`. Applying a negative value reduces the angular velocity by the specified amount.

`item`

The dynamic item whose angular velocity you want to increase (or decrease).
