Question

thick wire is twisted several times. will it have energy why

Answer 1

when a thick wire is twisted, potential energy gets stored in it. this is because when a wire is twisted work is done to twist it by the application of force. this work gets stored inside the wire in the form of potential energy which is released when the wire rewinds.

Answer 2

When the thick wire is twisted several times, the potential energy is stored in it and when we release it comes in its same position this is why it have energy.
