Consider a pulley fixed at a typical Indian well onwhich a rope is wound with one end attached to a bucket. When the bucket is released, the pulley starts rotating. As the bucket goes down, the pulley rotates more rapidly till the bucket goes into the water. Take the pulley as the system. The centre of mass of the pulley is at its geometrical centre which remains at rest. However, the other particles of the pulley move and are accelerated. The pulley is said to be executing rotational motion. 'oAlso, the rotational motion is nowt uniform. Since acm = 0, the resultant external force F acting on the pulley must be zero. Even then the pulley is not in rotational equilibrium. We shall now study this type of motion.
