The combination of rotational motion and the translation motion of a rigid body is known as rolling motion.
The kinetic energy associated with a body rolling is the sum of the translational and rotational kinetic energies, i.e., K.E of rolling
- When a body rolls down an inclined plane (θ) without slipping, the velocity on reaching the ground is,
Where h is the vertical height of inclined plane and K is the radius of gyration of the rolling body.
- The acceleration of a body rolling down an inclined plane is given by
