Question

when a battery is used to power a toy car, its chemical energy is transformed into which form of energy first?
light
electrical
mechanical
potential

Explanation:

A battery stores chemical energy. When it powers a toy car, through an electrochemical reaction inside the battery, the chemical energy is first converted into electrical energy. This electrical energy then can be further transformed (e.g., into mechanical energy to move the car). Light energy would be a by - product in some cases (like if there are lights on the toy) but not the first conversion. Potential energy is a more general term and not the immediate conversion from chemical energy in a battery for a toy car.

Answer:

electrical
