Lesson: Elastic Potential Energy High School PhysicsPhysics
In this lesson, we will learn how to calculate the elastic potential energy stored in springs that are not at their equilibrium length.

The keys on a computer keyboard contain small springs that compress by 4.8 mm when a key is pressed. On a particular day, 12,500 keystrokes are made on the keyboard. The springs in the keys each have a constant of 2.5 N/m. How much energy was supplied to make all the keystrokes performed that day?
A spring with a constant of 16 N/m has 98 J of energy stored in it when it is extended. How far is the spring extended?
A spring has 50 J of energy stored in it when it is extended by 2.5 m. What is the spring’s constant?
