Energy Transfer Basics
What is energy transfer?
The transformation of one form of energy into another, or the movement of energy from one place to another.
List three examples of energy.
Electrical, Chemical, Mechanical, Nuclear, Sound, Thermal, Radiant, Kinetic, Potential
Give an example of energy transfer in a light bulb.
Electrical to Radiant(light)/Thermal
What are the energy transformations in a toaster?
Electrical to Thermal (heat)
My teachers name is...
Miss Atchison
What is the Law of Conversation of Energy state?
Energy cannot be created nor destroyed, only transformed.
Explain the difference between potential and kinetic energy.
Potential is stored energy, and kinetic is energy in motion/being used.
Explain how energy is transferred in a battery-operated toy car.
What are the energy transformations in a cell phone?
Electrical to Chemical to Radiant (light)
What is an example of Chemical to Electrical energy?
Answers may vary.
Example: A battery in a cell phone.
Give an example of energy transfer from one object to another.
Answers will vary.
Give an example of energy stored in chemical form.
A Battery
Describe the energy transfer involved in boiling water on an electric stove.
Electrical to Thermal
What are the energy transformations in lightning?
Electrical to Radiant (light)
Compare potential and kinetic energy. (2 differences, 2 similarities).
Both forms of energy, both are ability to do work, both measured in joules.
One is moving energy, one is stored energy. One includes heat and light, one includes chemical and gravitiational.
RANDOM QUESTION:
How many countries are in the Commonwealth? closest wins

Describe how energy is stored in a compressed spring.
This potential energy is stored in the spring as elastic potential energy, and the amount of energy stored is proportional to the amount of compression or stretching that has been applied to it. The energy will become kinetic when the spring is released.
Discuss how energy is transferred in a wind turbine.
Mechanical to Electrical
What are the energy transformations in a hot air balloon?
Potential to Thermal/Sound/Kinetic
Explain what happens to the transfer of energy of a music speaker at a concert.
The speaker is plugged in to create electrical energy and turned into sound when music comes out of the speaker.
Example: Electrical Energy to Sound Energy
How tall is Uluru?
Closest wins
863 m
Discuss how energy is stored in food.
Energy in food is considered potential chemical energy. When food is digested and the energy is being used in your body, the energy is considered kinetic and can be used for activities such as biking which is mechanical.
Explain the energy transfer process in a solar panel.
Radiant (light) to Electrical
What are the energy transformations in a match?
Chemical to Thermal (heat) /Radiant (light)
What is the definition of energy?
The ability to do work.
