Lesson 8-4: Harmonic Motion


Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

Objective:

The student will be able to solve problems involving harmonic motion.

  1. Click the "Pull the Spring" button. The weight at the end of the spring will be pushed up, contracting the spring. The energy in the spring will push the weight down passed equilibrium and contract and pull the weight up. The height of the weight (0 being its equilibrium position) is graphed over time.
  2. How long does it take the weight to return to its original position?
  3. The animation runs for 20 seconds, how many cycles of stretch, compress, and back to equilibrium, are completed in the 20 seconds?
