Question

what type of potential energy is stored in a watch​

Answer 1

Answer:

Elastic potential energy

Elastic potential energy is a kind of potential energy stored as a result of deformation of an elastic object, such as stretching or compressing of rubber bands, springs and bungee cords. The more an object is stretched, more is its elastic potential energy. In a spring based watch, mainspring powers the watch.

Answer 2

Answer:

In a watch, the spring is allowed to move in a regulated way. Instead of just accelerating and releasing all the energy at once, there is a mechanism in the watch that smooths out the motion, providing a constant rate of rotation for some amount of time, after which you need to wind the watch spring up again So, the potential energy stored in a watch is spring energy
