Kinetic energy acquired by mass m travelling distance d from rest under a constant force F is directly proportional to:

G1 Physics · Accepted Answer

Step 1 — Principle: The net work on a body equals its change in kinetic energy: Wₙₑₜ = Kf − Ki. Step 2 — Working: Work–energy theorem gives K=Fd from rest. Step 3 — Working: for fixed force and displacement it does not depend on mass, so K∝m⁰. Correct answer: B — m⁰.
