# applyImpulse(_:at:)

Applies an impulse to a specific point of a physics body.

## Declaration

```swift
func applyImpulse(_ impulse: CGVector, at point: CGPoint)
```

## Parameters

- `impulse`: A vector that describes how much momentum to impart to the body. The impulse is measured in Newton-seconds.
- `point`: A point in scene coordinates that defines where the impulse was applied to the physics body.

## Discussion

Discussion Because this impulse is applied to a specific point on the object, it may change both the body’s velocity and angular velocity.
