# Simple Pendulum - Mass on a String

### Objective 1: To identify the simple pendulum as another example of simple harmonic motion

### Objective 2: To derive the restoring force for a simple pendulum

### A simple pendulum or a mass on a string is another example of simple harmonic motion. The following illustration shows the force diagram and quantities important for evaluating the periodic motion of a simple pendulum.

### The restoring force for a simple pendulum is the relation F = mgsin(theta)

### m - mass of the pendulum bob

### L - length of the pendulum from pivot to bob's center of mass

### g - acceleration of gravity

### theta (angle) - angular displacement of the pendulum

### s - linear displacement

### T - Tension
