• A torque is produced when a force is applied with “leverage.”– Ex. You use leverage
when you pull a nail from a piece of wood with a hammer. The longer the hammer, the greater the leverage.

Torque = Force x Lever arm

• An object rotating about an axis tends to keep rotating about that axis..
• Rotational Inertia – The resistance of an object to change in its rotational motion.– As an object moves
closer to the center, the rotational velocity increases.
