# Force effects

Control the movement of virtual objects with forces.

## Overview

Overview Create various types of force effects, such as vortex, drag, and turbulence. Add a force effect to a scene by creating a structure that adopts ForceEffectProtocol, and attaching it to an entity with a ForceEffectComponent.

## Topics

### Force effect components
