This resource is a Java applet-based module relating to the simple harmonic motion produced by a block on a frictionless spring. It features a rich array of tools: motion graphs, energy graphs, vector components, reference circle, zoom toggle, and a data box that displays amplitude, angular frequency, displacement from equilibrium, phase angle, velocity, and acceleration of the oscillating block. Users control the spring constant, mass of the block, and amplitude of the oscillation. A comprehensive help section provides detailed directions and lesson ideas for instructors.

This simulation is part of a larger collection of physics resources sponsored by the MAP project (Modular Approach to Physics).

Editor's Note:This is one of the best resources we've found for exploring simple harmonic motion and its sinusoidal nature. It can be adapted for course levels ranging from 9th grade physical science to calculus-based college physics courses. It covers kinematic properties, the dynamics of SHM, and explicit diagrams on sine/cosine functions illustrated through the unit circle. It will help learners understand that SHM is a motion identical to the projection of a uniform circular motion onto a straight line (Math Common Core F-TF.2, F-TF4, High School Trigonometric Functions)

9-12: 2A/H1. Mathematics is the study of quantities and shapes, the patterns and relationships between quantities or shapes, and operations on either quantities or shapes. Some of these relationships involve natural phenomena, while others deal with abstractions not tied to the physical world.

4. The Physical Setting

4E. Energy Transformations

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.

4F. Motion

6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.

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.

11. Common Themes

11B. Models

6-8: 11B/M2. Mathematical models can be displayed on a computer and then modified to see what happens.

6-8: 11B/M4. Simulations are often useful in modeling events and processes.
