jay bought a toy car. to make the car move, he must turn a key attached to a spring. turning the key winds the spring tight. the toy car moves when the key is released and the spring unwinds. whats the main transformation of energy in this example?\na. chemical energy to electric energy\nb. chemical energy to motion energy\nc. electric energy to motion energy\nd. electric energy to potential energy
Answer
Brief Explanations:
When the key is turned to wind the spring, work is done and elastic - potential energy is stored in the spring. When the key is released and the spring unwinds, the elastic - potential energy is converted into kinetic energy (motion energy) of the toy car. There is no chemical or electric energy involved in this process.
Answer:
No option is correct as the main energy transformation is elastic - potential energy to motion energy. But if we assume the closest option, it is not among the given ones. If we had to choose from the given options, none of them are correct.
