# Hooke's law

F = -k*d
Relationship between applied force to a spring, its displacement and the spring consant.
Enter 'x' in the field to be calculated.

This tool is a Hooke's law calculator. This law explains the relationship between the force exerted on a spring, its displacement and the spring constant or its rate of stiffness.

F: Force in Newton (N)
d: displacement of the spring in meter (m)
k: the spring constant in newton per meter (N/m)

F = -k*d
