The combination approach using the kinetic energy of the center of mass plus the rotational energy about the cm axis often seems to be the easiest for beginning students since it simply adds the change in rotational energy term to the already familiar form of the work energy theorem. Finding vcm, solution 4.

Specifically, we will assume, albeit a bit naïvely, that all of the potential energy you start out with is nicely transformed into rotational kinetic energy (PE = KErot). We will then calculate the speed of the ball at the time of its release, and use the range equation to calculate the range of the projectile.

Since this is multiplied by w^2 = v^2/R^2 to determine the rotational kinetic energy, either approach gives you a kinetic energy expression that looks something like: Ek = 1/2(m + m(r/R)^2)v^2 for the combination of translational and rotational kinetic energies.

IX. Rotational kinetic energy and conservation of mechanical energy. Spinning objects have rotational kinetic energy which is a separate quantity from translational (linear) kinetic energy. Changes in rotational kinetic energy must be considered when analyzing conservation of mechanical energy. As with angular momentum, rotational kinetic ...

Rotational Kinetic Energy. The kinetic energy of a rigid object rotating about a fixed axis is the sum of the kinetic energies of the individual particles that collectively constitute the object. The sum in the expression farthest to the right is the object’s moment of inertia I for the axis of rotation.

Oct 05, 2014 · The hollow cylinder has a greater moment of inertial. Therefore, its rotational kinetic energy is greater than the rotational kinetic energy of the solid cylinder. Since the total energy of each rotating object is the same that leaves less translational kinetic energy for the hollow cylinder.
