Question

describe the mode of energy transformation in a mechanical clock

Answer 1

>In mechanical clock, when spring is revolved, it becomes a potential energy.
>When spring is released, it will converted in to kinetic energy, so that the hand of the clock is rotated.
>Chemical energy from human body to kinetic energy in the fingers.  
>Then the kinetic energy is converted into the spring potential energy. 
>The mechanical clocks have a pendulum that oscillates due to gravity.  
>In wristwatches and in pendulum clocks there is usually a spring inside.  
>The spring unwinds slowly and gives energy to the pendulum to continue oscillations.
