Question

Compare the role of moment of inertia in rotational motion with the role of mass in linear motion

Answer 1

Answer:

If moment of inertia is large then given torque will produce less angular acceleration. The expression for this fact is tau/I= alpha. So ,moment of inertia plays the same role for rotational motion as the mass plays the role for linear motion. ... The linear velocity is equal to rw where w is the angular speed.
