elastic potential energy Flashcards
1
Q
what is elastic potential energy
A
energy stored in an object when work is done on the object to change its shape
2
Q
what does the energy depend on
A
- extension or compression of the spring
- spring constant
3
Q

A
-measure of the stiffness of the spring
- force required to produce an extension of 1m
4
Q
what is extension
A
- how much length of spring has changed
