Question : A wound watch spring has ____ energy.
Option 1: electrical
Option 2: kinetic
Option 3: potential
Option 4: both kinetic and potential
Correct Answer: potential
Solution : The correct option is potential .
Potential energy exists in a wound spring. Until the spring is freed and begins to move, it has no kinetic energy. Thus, the spring stores energy in the form of potential energy, which it then distributes as kinetic energy to the moving components when it is unwound.
