Elastic Potential Energy

What is elastic potential energy?

The energy stored in an object when it is stretched or squashed

What is the spring constant?

A measure of how stiff a spring is

When discussing elastic potential energy, what does extension (e) mean?

How much longer or shorter the extension of an object is

When discussing elastic potential energy, what units should extension (e) be in?

Metres (m)

What is the formula for elastic potential energy?

E_e = ½ x k x e²

What is the formula that links force, spring constant and extension?

F = k x e

This is a force extension graph. What does the gradient of the straight part of the line tell you?

The spring constant

This is a force extension graph. What does the area under the curve tell us?

Elastic Potential Energy

This a force-extension graph. What do we call the point where the line transitions from straight to curved?

The elastic limit
