# damping

A factor that reduces the body’s linear velocity.

## Declaration

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

## Discussion

Discussion This property simulates the effect of fluid friction or air resistance on a body. A damping factor of 0.0 specifies no loss in velocity, and a damping factor of 1.0 prevents the body from moving. The default damping factor is 0.1.
