FAQs on Maharashtra Board Class 12 Solutions for Physics Chapter 1 Rotational Dynamics - PDF
1. A particle undergoes uniform circular motion. At which point on the plane of the circle will the angular momentum of the particle remain conserved?
The force will be able to pass through the circle’s centre. Hence there will be a conservation of angular momentum at its centre.
2. Mention the characteristics of circular motion.
It is an accelerated (change in direction of velocity) motion, and the motion is periodic in nature.
3. What is the moment of inertia?
The moment of inertia of an object is its resistance to change in its rotation
4. What is torque?
Torque is a twisting effect due to the force applied to any rotating object which is at a position r from its axis of rotation.
5. Give an example of rotation motion about a fixed axis.
The rotation of the minute and the hour hand in a clock or watch is an example of rotational motion about a fixed axis.
