Equilibrium position
The position where the object would rest if all energy was removed from the system.
Oscillations
Periodic back and forth motion.
Amplitude
The distance between the crest (or trough) of a wave and its equilibrium position.
Time period
The time taken to complete a full cycle.
Angular frequency
The angle covered by a simple harmonic motion oscillator per second.
Simple harmonic motion
Oscillations around an equilibrium position where the displacement is proportional to the negative acceleration.
Energy in a mass-spring system/Pendulum
Elastic potential energy - maximum at the ends, zero at equilibrium
Kinetic energy - maximum at equilibrium, zero at the ends
Total energy - constant
