elastic potential energy Flashcards
1
Q
what is elastic potential energy? (free eScience def)
A
when putting energy in to stretch a spring, it stores this energy, we call this energy elastic potential energy
2
Q
when a force is applied to a spring to make it strech, the strech is called ______
A
it is called an extension
3
Q
if too much force is applied, (not only is the extension no longer proportional to the force applied) the spring also becomes stretched beyond the limit of proportionality which means…
A
it will not return to its original length if the force is taken away
4
Q
the elastic potential energy equation
A
Ee = 0.5 x k x e(2)
0.5 times the spring constant (N/m) x the extension squared
