Energy: Forms, Transformation, Transfer, and Conservation
Energy can be transferred from one system to another (or from a system to its environment) in different ways: by…
Item NG055002: Energy is transferred when a battery is connected to a light bulb in a complete circuit, and energy is transferred when wind causes a windmill to rotate.
Consider the following situations:
Situation 1: A battery is connected to a light bulb in a complete circuit, and the light
bulb lights up.
Situation 2: Wind causes a windmill to rotate.
Is energy being transferred in either of these situations?
- Energy is transferred in both situations.
- Energy is NOT transferred in either situation.
- Energy is transferred when a battery is connected to a light bulb in a complete circuit, but energy is NOT transferred when wind causes a windmill to rotate.
- Energy is transferred when wind causes a windmill to rotate, but energy is NOT transferred when a battery is connected to a light bulb in a complete circuit.

- PS3.B Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light. The currents may have been produced to begin with by transforming the energy of motion into electrical energy.
PS3.C When objects collide, the contact forces transfer energy so as to change the objects' motions.
