Look around the room. Provide an example of something with POTENTIAL energy and then describe it transformed to KINETIC energy.
__________________ --> ___________________
Come up with your own example of THREE transformations of energy.
(Hint: read the examples above, but you can't use them as yours.... maybe use how your phone works.)
_________--> _________--> _________
What is the one source that all energy can be traced back to?
Provide a second example of something with POTENTIAL energy and then describe it transformed to KINETIC energy.
______________--> ______________
How could you make one of your Potential Energy examples have MORE POTENTIAL energy?
Which of your two KINETIC ENERGY examples has MORE kinetic energy? Why?
What IS energy efficiency?
If something is ENERGY EFFICIENT, it:
Choose any electric appliance in your home and explain to me how to make it run more EFFICIENTLY.
For the next 8 questions, you have to find the answers in the 3 pages of text above.
What is created when electrons spin around the nucleus of an atom?
A moving magnetic field can pull or push ______.
What is a generator?
When an electromagnetic shaft rotates, what happens?
Most of the electricity in the United States is produced in _____ ______.
What is used burned in a furnace to heat the water in a boiler create steam in order to turn a turbine?
What are the 3 fossil fuels?
(Hint: they are italicized)
So how does a FUEL CELL work? The concept is the electrons run through the wire creating the power for the car, and these electrons come from the splitting of ________ from the water (H2O) in the air.
The Electric Car Electric cars operate using electric motors instead of internal combustion engines found in gasoline cars. An electric motor uses energy from the car's battery pack to produce rotational motion, which enables the car to move. Recharging the battery can be done by plugging the car into an electrical outlet or through specialized charging stations.
Electric cars use a motor but instead of a gasoline-based combustion engine, it uses the power from a rechargeable ________.
Hybrid Cars Hybrid cars are designed with a purpose: to reduce fuel consumption and decrease harmful emissions. Unlike conventional cars that solely rely on gasoline engines, hybrid cars are equipped with an electric motor that supplements the gasoline engine's power. This electric motor is powered by a battery, which is charged either by regenerative braking (like when the car repeatedly stops or slows down the car) or by the gasoline engine itself.
Hybrid cars also use an electric motor but they do not have to be plugged in to get energy. Instead, they get energy from either gasoline or using the kinetic energy from regenerative _________!
