Does an elongated spring have 0 elastic potential energy?

Correct A spring which follows Hooks Law has elastic potential energy which is given by the following equation: PE=(1/2)kx^2 k is spring constant and x is deformation. Spring which is elongated x has positive value. read more

A spring which follows Hooks Law has elastic potential energy which is given by the following equation: PE=(1/2)kx^2. k is spring constant and x is deformation. Spring which is elongated x has positive value. This implies that elongated spring has elastic Potential energy. Unstreched spring has zero elastic potential energy. read more

Definition: The spring constant, k, is a measure of the stiffness of a spring (large k stiff spring, small k soft spring). To compress a spring by a distance x we must apply a force F ext = k x. read more
