Asked in ETEA MDCAT 2017 2017Moderate

The moment of inertia of an object does not depend upon:

Correct answer: C. Angular velocity

  • A. Mass of an object
  • B. Mass of distribution
  • C. Angular velocity
  • D. Axis of rotation

Explanation

The moment of inertia Iof an object is a measure of its resistance to changes in angular velocity. It depends on the mass of the object and how that mass is distributed around the axis of rotation, but it is not influenced by the current angular velocity. Therefore, option c is correct.

About Angular and Linear Quantities

Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
