A body moving in a circular path with constant speed has:
Correct answer: B. Variable acceleration
- A. Constant acceleration
- B. Variable acceleration
- C. Constant retardation
- D. Variable speed and constant velocity
Explanation
In uniform circular motion, the acceleration is variable. The centripetal acceleration remains constant in magnitude but changes direction continuously, always pointing towards the center of the circular path.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
