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?
Ee = 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
