Energy: Forms, Transformation, Transfer, and Conservation
When objects collide, contact forces can transfer energy from one object to another resulting in a change in the…
Item NG059003: Energy is transferred when a battery is used to power a cell phone, and energy is transferred when the sun shines on a plant.
Consider the following situations:
Situation 1: A battery is used to power a cell phone.
Situation 2: The sun shines on a plant.
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 in Situation 1, but energy is NOT transferred in Situation 2.
- Energy is transferred in Situation 2, but energy is NOT transferred in Situation 1.

- PS3.B Light also transfers energy from place to place.
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.
