# 8: Small Oscillations


• 8.1: Simple Harmonic Motion
Restoring forces cause objects to oscillate back-and-forth across the equilibrium point. We will look at a specific class of restoring forces, which cause a common type of oscillatory motion.
• 8.2: Other Restoring Forces
Simple harmonic motion arises from restoring forces other than masses on springs. Here we explore a couple of examples.
• 8.3: Damping and Resonance
Elastic forces are conservative, but systems that exhibit harmonic motion can also exchange energy from outside forces. Here we look at some of the effects of these exchanges.
• 8.4: Coupled Oscillators and Normal Modes
