Calculate the instantaneous acceleration of an object in simple harmonic motion. Acceleration is proportional to displacement and directed toward the equilibrium position.
Enter your values below
Maximum displacement from equilibrium
Angular frequency of oscillation
Time at which to evaluate acceleration
Initial phase (default: 0)
How this calculator works
Acceleration equals negative amplitude times angular frequency squared times cosine of angular frequency times time plus phase. It is always directed toward equilibrium.
