For a disk of mass, M, and radius, R, the moment of inertia, I, is I=MR2/2. If the disk is spinning with angular speed, П‰, its rotational kinetic energy is K.E. = IП‰2/2. The angular speed of a disk is related to the speed (V) of its outer edge by, П‰ =V/R.

Rotational inertia plays an important role in both of these phenomena. The rotational inertia of an object depends on the mass and the distribution of mass. In general, the more compact an object, the less rotational inertia it has. Theoretically, the rotational inertia, I, of a ring is given by procedure until the mass comes back to within 3-5 centimeters of its starting point.

Physics 2A Rotational Motion and Moment of Inertia В©2003 Las Positas College, Physics Department Staff Revised 10/04/2010 В©WMPezzaglia 4 of 10 вЂњAny objectвЂќ really means вЂњany object with massвЂќ, which is usually a safe assumption.

An object with more mass will have more rotational inertia, but the way the mass is distributed around the rotation point also has an effect on rotational inertia. If your mass is a long way away K = ВЅ I П‰2 Rotational Kinetic Energy where: I = m r2 I is the rotational inertia of a point mass. As you can see, the rotational inertia of a point mass depends only on its mass m and its distance r from the axis it is rotating about. Now, let me emphasize something about that last calculation.

The Moment of Inertia is the property of a body which measures its ease or resistance to change in angular velocity. We will be using mainly a cylindrical ring and a sphere in our experaments. In the first part of our lab a rotating solid cylindrical drum with a hollow body drum given a rotational velocity from a falling mass.
