## Calculator Use

This calculator finds the missing variable in the physics equation for Hooke's Law Fs = -kx, when two of the variables are known.

Hooke's Law states that the force needed to extend or compress a spring is directly proportional to the distance the spring is stretched or compressed.

This means that there is a linear relationship between the force required to stretch a spring, and the length the spring is stretched.

## Hooke's Law Equation

$$F_{s} = -kx$$

The Hooke's Law Calculator uses the formula Fs = -kx where F is the restoring force exerted by the spring, k is the spring constant and x is the displacement, or distance the spring is being stretched.

### Variables in Hooke's Law Equation

• Fs = spring force
• k = a spring constant
• x = displacement

The equation can also be stated:

$$F = kx$$

Where F is the force exerted on the spring, k is the spring constant and x is the displacement.

You might see this equation in the case where the problem is in determining what is the force pulling on or compressing the spring.
