Elastic Potential energy Flashcards
1
Q
What is elastic potential energy?
A
The energy stored in an object when you squash it or spring it
2
Q
What does Ee stand for?
A
Elastic potential energy
3
Q
What does k stand for?
A
Spring constant
4
Q
What does e² stand for?
A
extension²
5
Q
what else do you have to times e² and k by to get Ee
A
1/2
6
Q
How do you calculate elastic potential energy?
A
Ee=0.5XkXe²
7
Q
How do you calculate spring constant?
A
k= Ee/0.5Xe²
8
Q
How do you calculate the extension?
A
e=√Ee/0.5Xk
OR
e²=Ee/0.5Xk
