13 of 15
when a battery - operated train is turned on, it moves along the track. energy is transformed as this happens. place the types of energy in the order that they occur.
:: mechanical energy
:: chemical energy
:: electrical energy

Explanation:

Step1: Identify initial energy

Batteries store chemical energy. So first energy is chemical energy.

Step2: Energy conversion in battery operation

When the train is turned on, the battery's chemical energy is converted to electrical energy to power the train's motor. So second energy is electrical energy.

Step3: Energy for motion

The electrical energy is then converted to mechanical energy to make the train move (kinetic energy, a type of mechanical energy). So third energy is mechanical energy.

Answer:

First box: chemical energy, Second box: electrical energy, Third box: mechanical energy
