# Elastic Potential Energy

Written by Jerry Ratzlaff on . Posted in Fastener

Elastic potential energy, abbreviated as PE, is the energy stored in objects as the result of deformation, such as a spring when stretching or compressing.

## Elastic Potential Energy formula

 $$\large{ PE = \frac {1}{2}\; k_s\; x^2 }$$

### Where:

 Units English Metric $$\large{ PE }$$ = elastic potential energy $$\large{lbf-ft}$$ $$\large{J}$$ $$\large{ x }$$ = length or displacement $$ft$$ $$m$$ $$\large{ k_s }$$ = spring constant $$\large{\frac{lbf}{ft}}$$ $$\large{\frac{N}{m}}$$
