Answer:
A. Potential energy
Explanation:
SHM = Simple Harmonic Motion (Hooke's Law)
its when spring goes up & down or side to side & you can show the motion via wave on graph... that wave is a sine wave
When is kinetic energy maximum in SHM?
Kinetic energy is a maximum when the potential energy is a minimum, and when the mass undergoing simple harmonic motion has the greatest speed.
For a mass-spring system, this occurs when the spring is neither stretched nor compressed; this is at the so-called equilibrium position, since the net force on the mass is zero.
For a pendulum oscillating with a small angle, approximating SHM, maximum kinetic energy will occur as the pendulum passes through the lowest, vertical position.
Thus, in SHM generally, the kinetic energy is at a maximum twice per cycle.
