Stretching or squashing an object can transfer energy into its elastic potential energy store.
What is Elastic potential energy?
Stretching or squashing an object can transfer energy into its elastic potential energy store. Elastic energy is the mechanical potential energy stored in the material. Elastic energy occurs when objects are compressed, stretched or deformed.
Elastic potential energy equation
To calculate Elastic potential energy we use this equation.
$E_e = { 1 \over2} ke {^2}$
Elastic potential energy demo
In this tutorial you will learn how to calculate the energy stored in a stretched spring.
Chilled practice question
A spring is stretched 200 cm. The spring has a spring constant of 30 N/M. Calculate the stored elastic potential energy of the stretched spring.
Frozen practice question
Calculate the extension of a spring if it has a stored elastic potential energy of 540 J and a spring constant of 30 N/M.
Science in context
Stretching or squashing an object can transfer energy into its elastic potential energy store.
