Physics 312 Lecture: "Simple Harmonic Motion" Mar 27, 1998

• Simple harmonic motion (SHM) is a special type of oscillation
• SHM occurs when a system has a stable equilibrium, and a restoring force which is linearly proportional to the distance from that equilibrium
• Amplitude controls the maximum displacement from equilibrium
• Angular frequency controls the rate of oscillation
• Phase angle specifies the conditions at time = 0
• The square of angular frequency is equal to the force constant of an oscillator, divided by its mass

This lecture discusses material in Chapter 13 of Serway.
