Dive into the fascinating world of rotational mechanics, where torque is produced by leverage and objects tend to keep rotating about an axis. Understand how rotational inertia influences motion, with examples from ice skating, gymnastics, racing, and roller coasters. Discover the physics behind sports and have fun exploring the principles of torque and inertia.

Rotational Mechanics And the fun continues…
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
Torque = Force x Lever arm Torque
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. Rotational Inertia
