Simple Harmonic Motion – Concepts
... When the mass is motionless, its acceleration is zero. According to Newton’s second law, the net force must therefore be zero. There are two forces acting on the mass: the downward gravitational force and the upward spring force. See the free-body diagram in Figure 6 below. ...
