1. Mechanical energy: When the crank is turned, mechanical energy is being applied to the flashlight.
2. Kinetic energy: The mechanical energy from the crank is converted into kinetic energy, which causes the internal mechanism of the flashlight to spin.
3. Electrical energy: As the internal mechanism spins, it generates electricity which charges the battery of the flashlight.
4. Chemical energy: The electrical energy is stored in the battery as chemical energy, which can then be used to power the flashlight and emit light.
An electric flashlight can be charged by firing a crank. Identify the types and order of energy changed happening.
