Potential energy. is stored energy. It can be used to do work or converted to. another form of energy such as heat or kinetic energy. Kinetic energy. is the energy of a moving object. The motion can be rotational (like rolling) or translational (like sliding). Frictional forces. act against the motion of an object and slow it down. Purpose of ...

Kinetic Energy of Rotation. Consider the kinetic energy of a rotating rigid body: Since v = (r, and ( is the same for all particles, we have. is called the . rotational inertia. It tells us how the mass of the rotating body is distributed about its axis of rotation. In summary, and . For continuous bodies, Ring (axis) (diameter) Cylinder

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 ...
