Simple Harmonic Motion with Demonstrations

Description
To begin with Hooke's law is explained. A visual demonstration using spray paint and a spring shows what kind of solution to be expected. To explain the factors affecting the time period of a pendulum the presenter performs an experiment in which he physically swings along with a pendulum---don't miss the fun.
