Which of the following statements is true of a particle that is moving in simple harmonic motion?
A)The momentum of the particle is constant.
B)The kinetic energy of the particle is constant.
C)The potential energy of Earth-particle system is constant.
D)The acceleration of the particle is constant.
E)The force the particle experiences is a negative restoring force.

Question

Quizplus · Accepted Answer

In simple harmonic motion, the force acting on the particle is a restoring force that is always directed towards the equilibrium position and is proportional to the displacement from that position. This force is negative because it acts in the opposite direction of the displacement, aiming to restore the particle to its equilibrium position. The other options are incorrect because in simple harmonic motion, the momentum, kinetic energy, potential energy, and acceleration of the particle are not constant; they vary as the particle oscillates.
