To calculate the moment of inertia of a system by a dynamical method and compare it with an estimate based on point mass approximations. Introduction. The resistance to any change in rotation of a body is called its rotational inertia or moment of inertia. Just as mass resists any change in linear motion, so does moment of inertia resist any The moment of inertia is a measure of the way the mass is distributed on the object and determines its resistance to rotational acceleration. Every rigid object has a definite moment of inertia about any particular axis of rotation. Here are a couple of examples of the expression for I for two special objects:

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, ω, its rotational kinetic energy is K.E. = Iω2/2. The angular speed of a disk is related to the speed (V) of its outer edge by, ω =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 ©2003 Las Positas College, Physics Department Staff Revised 10/04/2010 ©WMPezzaglia 4 of 10 “Any object” really means “any object with mass”, 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.
