Simple Harmonic Motion

... Title: Simple Harmonic Motion Objective: Show that the motion of a simple pendulum is simple harmonic, sinusoidal and independent of amplitude. Introduction: Simple harmonic motion is defined as the motion of a particle whose acceleration is always directed towards the equilibrium point and is directly proportional to the displacement of the particle from that point. In the experiment, a simple pendulum will be stuck on the paper tape. the motion of simple pendulum is then investigated. Procedure: 1. Using a string of length 1.2m,suspend the 0.5 kg ringed mass vertically from the retort stand-and-clamp. 2. Adjust the position of the clamp so that the mass is about 5 cm above the ground. 3. Cut a ticker-tape of length about 1 m. Write down "Start" on one end and stick that end of the tape to the bottom of the mass. 4. Pass the free end of the tape through the ticker-timer
