# Joints

> Apply and configure joints that connect GameObjects and simulate physical forces for pivoting, movement, and restriction.

A Joint connects a Rigidbody to another Rigidbody, or to a fixed point in space. Joints can apply forces that move rigid bodies, and joint limits can restrict that movement.

You can configure Joints via the [`Joint`](/engine/6000.6/script-reference/unityengine/joint.md) class, or the appropriate Joint component.
