About this Simulation

This simulation reveals the deep connection between circular motion and simple harmonic motion (SHM). By projecting the position of an object moving uniformly in a circle onto a vertical line, learners observe how this projection oscillates back and forth—the essence of SHM. Adjust velocity, amplitude, and phase to explore how circular motion generates periodic oscillations.

Learning objectives: Understand that SHM is the one-dimensional projection of uniform circular motion | Relate circular motion parameters to oscillation amplitude, frequency, and phase | Visualize and predict the behaviour of oscillating systems using the circle model.
