Question

Rolling motion is

Answer 1

Rolling motion:

It is the motion in which the mix of rotation and translation has occurred.

A diagram to represent the rolling motion:

The formula of rolling motion:

$K=\frac{1}{2}m{v^2}_{cm}+\frac{1}{2}I{\omega }^2$

where $K$ is the total kinetic energy,

$m$ is the mass of the body,

$v_{cm}$ is the velocity of the center of mass of the body,

$I$ is the moment of inertia of the body,

$\omega$ is the angular velocity of the body.
