An electric flashlight can be charged by firing a crank. Identify the types and order of energy changed happening.
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.
