Q. Which physical quantity is analogous to mass in rotational motion?

कौन सी भौतिक राशि घूर्णी गति में द्रव्यमान के अनुरूप होती है?

Torque
टॉर्कः

Moment of inertia
निष्क्रियता के पल

Angular velocity
कोणीय वेग

Angular momentum
कोनेदार गति

In linear motion, force = mass × acceleration.
In rotational motion:

\text{Torque} = \text{Moment of Inertia} \times \text{Angular Acceleration} \Rightarrow \tau = I\alpha

Hence, moment of inertia plays the same role as mass in resisting angular acceleration.
