elastic potential energy Flashcards
1
Q
define doing work
A
applying a force to change the length of a spring
2
Q
define elastic potential energy
A
the energy stored in stretched springs
3
Q
what is the relationship between force applied and extension
A
the extension is directly proportional to the force
up to the limit of proportionality as the spring has been stretched past the limit of proportionality so will not return back to it’s original shape
4
Q
equation for elastic potential energy
A
elastic potential energy = 0.5 x k x e squared
5
Q
what are the units for spring constant (K)
A
n/m
6
Q
what are the units for extension (e)
A
metres (m)
