If a body is moving in a circular path with constant speed, then the
Correct answer: A. Velocity and acceleration are perpendicular to each other
- A. Velocity and acceleration are perpendicular to each other
- B. Velocity and acceleration are parallel to each other
- C. Velocity and acceleration are anti-parallel
- D. Both have zero magnitude
Explanation
The velocity of an object in circular motion is always tangent to the circle, while the acceleration is always directed toward the center of the circle. This means that the velocity and acceleration vectors are always perpendicular to each other.

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.
