Question

when we wind a watch the mascular energy changes into

Answer 1

Explanation:

We know that total energy is kinetic energy plus potential energy.

Now, kinetic energy is

E=

2

1

MV

2

Which depends on velocity. In watch there is no displacement in the knob, hence velocity is zero. So there is no kinetic energy. Only potential energy is there.

Answer 2

Answer:

muscular energy changes into kinetic energy of wind.
