| Student Manual |  Webcams are easily available and cheap every-day use items. This innovative experiment uses a webcam to monitor the oscillations of a body attached to a spring, negotiating simple harmonic motion. The effect of the viscous force of a liquid on the damping of the harmonic motion is also investigated. |
