Amplitude, Period, Frequency, Angular Frequency

Overview

Amplitude A: maximum displacement from equilibrium (m). Period T: time for one complete oscillation (s). Frequency f: oscillations per second (Hz). Angular frequency ω = 2π/T = 2πf (rad/s). All three are related: T = 1/f = 2π/ω. These describe the timing of oscillation without reference to the restoring force.
