Hooke's Law Calculator
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
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:
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.
