Solution
Correct Answer:
Rotational kinetic energy
The Work-Energy Theorem for Rotation states that the work done by a net torque on a rigid body is equal to the change in its rotational kinetic energy: W=∫τdθ=ΔKrot=21Iωf2−21Iωi2 This is the rotational equivalent of W=Fd=ΔKtrans.
This medium difficulty physics question is from the chapter rotational motion, covering the topic of work-energy in rotation. It appeared in the 2025 exam.
