# Spring Potential Energy

Written by Jerry Ratzlaff on . Posted in Fastener

Spring potential energy, abbreviated as U, is the stored energy as a result of the objects elastic deformation.

### Spring Potential Energy formula

$$\large{ PE_s = \frac {1}{2} \; k_s \; l_s^2 }$$

Where:

$$\large{ PE_s }$$ = spring potential energy

$$\large{ k_s }$$ = spring force constant

$$\large{ l_s }$$ = spring stretch length
