Elastic Potential Energy Calculator

Formula

The formula to calculate the Elastic Potential Energy (U) is:

\[ U = 0.5 \cdot k \cdot y^2 \]

Where:

\( U \) is the Elastic Potential Energy (Joules).
\( k \) is the Spring Constant (N/m).
\( y \) is the Distance Stretched (meters).

What is Elastic Potential Energy?

Elastic potential energy is specific potential energy when applied to spring systems. When springs are compressed or stretched, they store potential energy within their elastic structure.

Example Calculation

Consider an example where:

Spring Constant (k): 200 N/m
Distance Stretched (y): 0.5 meters

Using the formula to calculate the Elastic Potential Energy:

\[ U = 0.5 \cdot 200 \cdot 0.5^2 = 25 \text{ Joules} \]

This means that the elastic potential energy for this example is 25 Joules.
