How to use the spring potential energy calculator
Find the energy stored in a spring compressed or stretched by a given distance. Enter spring constant, compression or extension in the fields above; the stored energy are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “energy stored in spring”, “compressed spring energy”, “elastic energy ½kx²”, “calculate spring potential energy”, “find stored energy”.
Formula
Variables
- k — Spring constant (N/m)
- dx — Compression or extension (m)
Worked example
With spring constant = 200 N/m, compression or extension = 0.1 m, the calculator gives stored energy ≈ 1 J; stored energy ≈ 1,000 mJ.
Frequently asked questions
What is the spring potential energy calculator used for?
Find the energy stored in a spring compressed or stretched by a given distance. It helps with questions such as “energy stored in spring”, “compressed spring energy”, “elastic energy ½kx²”.
What is the formula for the spring potential energy calculation?
Stored energy (J) = 0.5 × k × dx × dx. Stored energy (mJ) = [Stored energy] × 1000. Here k is spring constant (N/m), dx is compression or extension (m).
What inputs do I need for the spring potential energy calculator?
You need spring constant in N/m, compression or extension in m. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the spring potential energy calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the spring potential energy result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
