P2.3.2 - Stretching materials and storing energy Flashcards
1
Q
How do you calculate the energy transferred in stretching a spring?
A
energy transferred in stretching(J) = 0.5 x spring constant(N/m) x (extension(m))2
2
Q
What is elastic potential energy?
A
The energy stored by an elastic body, that has been stretched
3
Q
