Harmonic Motion

In Lab 11, you will study harmonic motion. You will be measuring the position as a function of time of a glider attached by springs to the ends of an air track under various conditions. (We use an air track because these are very friction sensitive studies and the air track provides a cushion of air for the glider to ride on, re ...continues
