If the displacement of a body is proportional to the square of time, then the body is moving with:
AUniform velocity
BUniform acceleration
CVariable acceleration
DDecreasing velocity
✓ Correct Answer: B — Uniform acceleration
s = 0.5at^2 (if u=0), so s is proportional to t^2 when acceleration 'a' is constant.
