Question: About Simple Harmonic Motion (SHM) is wrong:
A.The restoring force is linear, the net force is toward the equilibrium position and is linearly proportional to the distance From equilibrium.
B. The amplitude is the distance from the actual position to the equilibrium position.
C. A mass on a vertical spring oscillates with simple harmonic motion and gravity is the restoring force.
D. Oscillation about an equilibrium position with a linear restoring force is always SHM.
E.Can occur when a system has a restoring force that pushes it back toward equilibrium.
