# applyForce(_:at:duration:)

Creates an action that applies a force to a specific point on a node’s physics body.

## Declaration

```swift
class func applyForce(_ force: CGVector, at point: CGPoint, duration: TimeInterval) -> SKAction
```

## Parameters

- `force`: A vector that describes how much force is applied in each dimension. The force is measured in Newtons.
- `point`: A point in scene coordinates that defines where the force is applied to the physics body.
- `duration`: The duration over which the force is applied to the physics body.

## Return Value

Return Value A new action object.

## Discussion

Discussion When the action executes, the force is applied continuously to the physics body for the duration of the action. Because the force is applied to a specific point on the body, it may impart both linear acceleration and angular acceleration. This action is reversible; it applies an equal force in the opposite direction.
