Spring Calc
Three calculators in one panel. Hooke's law Solves F = k · x for any unknown; reports stored energy U = ½ k x² .
About this tool
Three calculators in one panel.
Hooke's law
Solves F = k · x for any unknown; reports stored energy U = ½ k x².
Simple harmonic motion
Mass-spring period T = 2π√(m/k), frequency f = 1/T, angular frequency ω = √(k/m).
Two-spring combinations
Series k_s = k_a·k_b/(k_a + k_b); Parallel k_p = k_a + k_b.
