This web page provides a multimedia format for exploring simple harmonic motion. It includes background material on the basics of SHM, Chladni patterns, phasor addition, Lissajous figures, and more complex waveforms. Short video clips, still images, graphs, and diagrams are integrated with text and lecture presentations to promote understanding of each concept.
This tutorial is part of the PhysClip collection of web-based resources on introductory mechanics, electricity, and magnetism.
9-12: 4E/H1. Although the various forms of energy appear very different, each can be measured in a way that makes it possible to keep track of how much of one form is converted into another. Whenever the amount of energy in one place diminishes, the amount in other places or forms increases by the same amount.
6-8: 4F/M7. Wave behavior can be described in terms of how fast the disturbance spreads, and in terms of the distance between successive peaks of the disturbance (the wavelength).
9-12: 4F/H1. The change in motion (direction or speed) of an object is proportional to the applied force and inversely proportional to the mass.
9-12: 4F/H6c. The energy of waves (like any form of energy) can be changed into other forms of energy.
9. The Mathematical World
9B. Symbolic Relationships
9-12: 9B/H4. Tables, graphs, and symbols are alternative ways of representing data and relationships that can be translated from one to another.
