21Elasticity Hookes Law Young ModulusMedium1 mark
The graph shows the variation of the elastic potential energy stored in a spring with the square of the extension of the spring.
graph of elastic potential energy Ep in joules against extension squared in m²: a straight line through the origin reaching Ep = 0.48 J at extension squared = 0.04 m²
What is the spring constant of the spring?
