AIPMT PRELIMS 2005 Physics Rolling Motion MCQ Question
A drum of radius R and mass M, rolls down without slipping along an inclined plane of angle θ. The frictional force:
converts translational energy to rotational energy
dissipates energy as heat
decreases the rotational motion
decreases the rotational and translational motion
Correct Answer
Detailed Explanation
The frictional force provides the torque necessary for the drum to roll without slipping, converting translational energy into rotational energy.
