Simple Harmonic Motion Calculator
Find the position of an oscillator at a given time.
Simple harmonic motion describes oscillations like springs and pendulums.
The math behind it
x = A·cos(ωt) with ω = 2πf. The maximum speed is A·ω, reached as it passes through the center.
Worked example
A = 0.2 m, f = 1 Hz, t = 0.25 s → x ≈ 0 (passing center).
FAQ
What sets the frequency?
For a spring, f depends on stiffness and mass; for a pendulum, on length and gravity.
