# applyForce(_:at:duration:) Creates an action that applies a force to a specific point on a node’s physics body. ``` 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 A new action object. ## 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. --- Copyright © 2026 Apple Inc.
