Example 2: Spring-mass systemA mass suspended from a spring, displaced vertically and released to move freely to produce up and down motion
The model view of a mass suspended from a spring, displaced vertically and released to move freely to produce up and down motion with right panel showing the displacement, velocity and acceleration.
Q1: under what conditions would this vertical spring mass system’s motion be not well modelled as a simple harmonic motion?
H1: the model assumes the restoring force by the spring is F = -ky, it is always correct for any magnitude of oscillation y in real springs. Is it always valid in the real spring motion when the spring is hyper extending beyond the linear limits of Hooke's Law ?
