Apply MS 3b and MS 3c skills when calculating elastic potential energy.

When calculating elastic potential energy, it is essential to understand the relationship between the spring constant and the extension of the spring. The formula for elastic potential energy is given by Ee = 0.5 x k x e², where Ee is the elastic potential energy, k is the spring constant, and e is the extension. This equation shows that the energy stored in a spring increases with the square of the extension, meaning that doubling the extension results in more than double the energy stored. This principle is crucial for understanding how elastic materials behave under stress.
