Spring & Hooke's Law Simulator
Pull a mass on a spring and explore oscillation, period, damping and energy.
Displacement0 m
Spring force0 N
Period (2π√m/k)0 s
Frequency0 Hz
Total energy0 J
What you can learn
- Hooke's law: the spring force is F = −kx.
- The period is T = 2π√(m/k). A stiffer spring or a lighter mass oscillates faster.
- Energy swaps between kinetic and elastic potential, and damping slowly removes it.
Frequently asked questions
What is simple harmonic motion?
Motion where the restoring force is proportional to displacement, giving a smooth sine-wave oscillation. A mass on an ideal spring is the classic example.
Does amplitude change the period?
Not for an ideal spring. The period depends only on mass and spring constant.
