Calculate the force exerted by a spring using Hooke's law F = -kx. Determine the restoring force, spring constant, or displacement for an ideal spring.
Enter your values below
Magnitude of spring force
Stiffness of the spring
Extension or compression from equilibrium
How this calculator works
Hooke's law states that the force exerted by a spring is proportional to its displacement from equilibrium. The negative sign indicates the restoring force opposes the displacement.
