Which one is constant for a satellite in orbit?
Correct answer: C. Angular momentum
- A. Velocity
- B. K.E
- C. Angular momentum
- D. Potential Energy
Explanation
The angular momentum of a satellite in orbit is constant. Angular momentum is a conserved quantity, and for an isolated system like a satellite in orbit, it remains constant unless acted upon by an external torque. As the satellite orbits around the central body, its angular momentum is conserved due to the conservation of angular momentum.

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.
