Question

what is the energy transformation while winding a toy???​

Answer 1

Answer -

At the beginning, the person has kinetic energy (chemical allows them to live, mechanical to move), and the toy has gravitational potential energy (assuming it is on an above-ground surface). As the person turns the handle, they apply mechanical energy onto the toy, which then gets mechanical energy too. As it moves across the surface, the toy experiences-although relatively little-thermal energy (friction force working against it). Finally, the handle unwinds through elastic potential energy.
