What is simple harmonic motion?
Simple harmonic motion is an oscillation where acceleration is directly proportional to displacement from equilibrium and always directed towards it. This is written a = −ω²x. The period does not depend on amplitude. A simple pendulum and a mass on a spring both show SHM, with T = 2π√(l/g) and T = 2π√(m/k).
Formula
a = −ω²x and T = 2π ÷ ω
