Simple Harmonic Motion (SHM)
Motion where the acceleration is proportional and opposite to displacement from an equilibrium position; defined by the equation: a = –ω²x.
Angular Frequency (ω)
A measure of how quickly an object oscillates in SHM
Time Period (T)
Time for one complete oscillation; T = 1/f = 2π/ω.
Displacement (x)
The distance and direction of the particle from its equilibrium position.
Amplitude (x₀)
The maximum displacement from equilibrium.
Phase Angle (ϕ)
Describes the initial angle of the sinusoidal function that defines SHM: x = x₀ sin(ωt + ϕ).
Total Energy in SHM (Eₜ)
Constant for an undamped system: Eₜ = (1/2)mω²x₀².
