# dampingRatio

The amount of drag applied, as a fraction of the amount needed to produce critical damping.

## Declaration

```swift
var dampingRatio: Double { get }
```

## Discussion

Discussion When dampingRatio is 1, the spring will smoothly decelerate to its final position without oscillating. Damping ratios less than 1 will oscillate more and more before coming to a complete stop.
