Hooke's Law Calculator

Hooke's law calculator calculates the force needed for the spring to extend or compressed.

How Hooke's Law Work?

Hooke's law is a theory of elasticity, when a force is applied to a spring, it makes the spring compressed or extend to a certain length, therefore it's also called the spring constant. Spring displacement is the difference between the initial spring and final spring length.

For example, if the final spring length is 1 meter, and the initial spring length is 0.2 meters, the spring displacement is 0.8 meters.

Hooke's Law Formula

Hooke's law formula is F=-kx
while k is the spring constant, and x is the spring displacement. The result is negative because the force needed for the spring to go in the opposite direction to its original length.
