Hooke's Law

Introduction to Hooke's Law Calculator

Hooke's Law is a principle of physics that states the force F needed to extend or compress a spring by some distance X is proportional to that distance. That is, F = k * x, where F is the force applied, k is the force constant of the spring (also known as the spring constant), and x is the extension (or compression) of the spring from its original length.

Parameter usage:

• forceConstant = spring constant (k), must be greater than 0.
• extension = extension or compression distance (x), must be greater than 0.

Example valid values:

• forceConstant = 300 N/m
• extension = 0.2 m

Output:

• force = force required (F)

Data validation

Checks are included to ensure both the force constant and extension are positive values.

Summary

This calculator determines the force required to either extend or compress a spring based on Hooke's Law, illustrating the proportional relationship between force and displacement.
