Online Elastic Potential Energy Calculator
Calculate elastic potential energy U = ½kx² (spring: k = spring constant, x = displacement).
Frequently Asked Questions
- What is k?
- Spring constant (stiffness), in N/m. Higher k means stiffer spring.
- What is x?
- Displacement from equilibrium (stretch or compression), in meters.
- Units?
- Use SI: k in N/m, x in m; U will be in joules (J).
