Work out mass spring oscillation instantly with clear inputs, formula shown and shareable results.
A mass on a spring oscillates at omega = sqrt(k/m), so a stiffer spring or a lighter mass raises the frequency. 0.5 kg on a 200 N/m spring gives 3.18 Hz. Gravity does not affect the frequency at all - it only shifts the equilibrium point down by mg/k, which is the static deflection shown here.
Angular frequency
omega = sqrt(k / m)
Period
T = 2 pi sqrt(m / k)
No. Gravity moves the rest position but the restoring force about that new position is still kx, so the frequency is unchanged.
Springs in parallel add their constants; springs in series reduce the effective constant. Doubling k raises frequency by only 41%.
