For a body moving with constant speed in a horizontal circle, which of the following remains constant?
Correct answer: D. Kinetic energy
- A. Velocity
- B. Acceleration
- C. Centripetal force
- D. Kinetic energy
Explanation
As K.E depends upon magnitude of velocity i.e. speed. In a horizontal circle as speed is constant so K.E remains constant.The correct answer is option D) Kinetic energy. In circular motion with constant speed, the kinetic energy of the body remains constant.

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.
