Overview

Simple Harmonic Motion(SHM) is represented here using a mass that is attached to a spring. The other end of the spring is fixed to the middle of a horizontal surface. In this model there is no friction. This SHM simulation was designed to help students better conceive the relationship between position, velocity and acceleration.

The simulation allows the student to vary the mass of the oscillating mass and the strength constant of the spring. Thus, the student will be able to make conjectures on subsequent motion as the inertia and net force have changed. These variances will help the student gain a deeper understanding of Newton's Laws.

Finally, the SHM simulation can be done in 2 dimensions creating elliptical motion. Newton wrote this is the Principia and the motion is similar to planetary orbits.
