Watch the following video tutorial on rotational inertia, which relates torque and acceleration.

[PDF of Slides]


• The greater the rotational inertia of an object, less it accelerates when acted on by a torque.
• Rotational inertia depends on: 1) Total mass of the object and 2) How the mass is distributed
• The farther the mass is from the axis of rotation, the larger the rotational inertia.
• If an object or character is top-heavy or tall then it tips over slowly due to its large rotational inertia.
