Passage
A torsion spring is twisted and held, like the spring in a clothespin.
How is energy stored and released in this case?
A
Twisting stores gravitational potential energy.
B
Twisting stores kinetic energy only.
C
Twisting stores chemical energy in the metal.
D
Twisting stores elastic potential energy in the deformed material, and release transforms it mostly into kinetic energy of the moving parts (plus some heat).
