Abstract
This pair of documents provide a basic introduction to simple harmonic motion and permit students to explore the effect of mass and force constant on this motion. The horun.mcd document permits students to create a simple animation of the harmonic motion of a diatomic molecule. The instructional document gives a foundation to harmonic motion in terms of Legrange's equation of motion. Elementary differential calculus is required. Mathcad 6.0+ is required to use the horun.mcd document. Student active learning is supported by a set of questions that direct their exploration of the harmonic oscillator concepts.
