The centripetal acceleration of a body moving at speed v in a circle of radius r is:

Answer: v²/r.

A v²/r
B v/r only
C vr only
D v²r only

Correct answer: A. v²/r

Explanation: Centripetal acceleration = v²/r, directed toward the centre.

Projectile trajectories launched at 15, 30, 45, 60, 75 and 90 degrees at the same speed, each annotated with range R, maximum height H and time of flight T, with coloured dots marking equal time intervals

Projectiles at equal speed: range is maximum at 45°, and complementary angles (30° and 60°) share the same range. Image: Cmglee, CC BY-SA 3.0, via Wikimedia Commons.

Concept context

Vectors, projectile motion, uniform circular motion, and relative velocity - the foundation of 2D kinematics for NEET and JEE.
