alleryIn a uniform circular motion, the SPEED is constant but velocity changes direction. The acceleration:
AIs zero
BPoints toward the center (centripetal)
CPoints outward
DPoints along the velocity
Answer & Solution
Correct answer: B. Points toward the center (centripetal)
Speed is constant but direction changes — so velocity changes.
This change in velocity is the acceleration, which always points toward the center of the circle (centripetal). Magnitude: a = v²/r.
