Question

A drum of radius R and mass M, rolls down without slipping along an inclined plane of angle θ The frictional force (A) converts translational energy to rotational energy (B) dissipates energy as heat (C) decreases the rotational motion (D) decreases the rotational and translational motion

Tardigrade Admin · Accepted Answer

When a body rolls down without slipping along an inclined plane of inclination θ, it rotates about a horizontal axis through its centre of mass and also its centre of mass moves. Therefore, rolling motion may be regarded as a rotational motion about an axis through its centre of mass plus a translational motion of the centre of mass. As it rolls down, it suffers loss in gravitational potential energy provided translational energy due to frictional force is converted into rotational energy.
