Elastic Potential Energy

Energy stored in a spring is proportional to the square of displacement.
U = ½kx²

Variables:

kSpring constant (N/m)
xDisplacement (m)

Example

Spring

Inputs:

k:100 N/m
x:0.5 m

Steps:

  1. 1.U = 0.5 × 100 × 0.5²
  2. 2.U = 12.5 J
Result:
12.5 J

Frequently Asked Questions

What is spring constant?

The spring constant (k) measures stiffness. Higher k means stiffer spring.
