Introduction
Hooke's Law Calculator — Spring force from stiffness and displacement. Enter Spring constant (N/m), Displacement (m) to get an instant, accurate result.
Formula
Hooke's law: F = k × x, where k is the spring constant and x is displacement from equilibrium.
Step-by-step
- Enter the Spring constant (N/m).
- Enter the Displacement (m).
- Click Calculate to see your result instantly.
Real-world example
Example: With Spring constant (N/m) = 200, Displacement (m) = 0.1, the Hooke's Law Calculator gives Force N: 20.
Frequently Asked Questions
What does the spring constant represent?
How stiff the spring is — a higher k means more force is needed to stretch or compress it the same distance.
Does this work for compression as well as stretching?
Yes, Hooke's law applies to both, as long as the spring stays within its elastic limit.
What inputs does the Hooke's Law Calculator need?
You'll need to provide: Spring constant (N/m), Displacement (m). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Hooke's Law Calculator?
The Hooke's Law Calculator applies the formula exactly as calculated — Hooke's law: F = k × x, where k is the spring constant and x is displacement from equilibrium. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Hooke's Law Calculator free to use?
Yes, the Hooke's Law Calculator is completely free, requires no signup, and runs instantly in your browser.
About the Hooke's Law Calculator
The Hooke's Law Calculator uses a real, verifiable formula — Hooke's law: F = k × x, where k is the spring constant and x is displacement from equilibrium. — so results are accurate every time, not an approximation.
