The acceleration in uniform circular motion always points:
ATowards the centre
BAway from the centre
CAlong the tangent
DStraight upward
Answer & Solution
Correct answer: A. Towards the centre
1. Speed is constant but direction keeps turning.
2. The change in velocity points inward.
3. So the acceleration is towards the centre.
