Potential Energy SPRINGS: the force (F) required to extend/compress a spring is proportional to the extension/compression (x>0): F x OR F = kx (Hooke's Law) k is called the force constant of the spring in [ N/m ] F x slope of line is k The work done in extending/compressing a spring is the area under the graph: W In this case,
