The moment of inertia of a body comes into play
In motion along a curved path
In linear motion
In rotational motion
None of the above
As we learnt in
Moment of inertia -
Moment of inertia (I) of a body is a measure of its ability to resist change in its rotational state of motion.
- wherein
Moment of inertia play the same role in rotatory motion as is played by mass in translatory motion .
The moment of inertia of a body comes into play in rotational motion.
