The two variables that affect kinetic energy.
What is mass and speed?
100
This is the Law of Consevation of Energy.
What is energy can not be created or destroyed?
100
Almost nothing is this since some energy is always lost to unwanted forms.
What is 100% energy efficient?
100
Recently, these have become more efficient and some people have begun to install them on their roofs.
What are solar cells or solar panels?
200
Four objects that emit that emit electgromagnetic energy.
What are television, microwave, light bulb (lamp), and the Sun?
200
This occurs when a brick falls off a house.
What is potential energy is converted to kinetic energy?
200
According to this, energy can never be destroyed.
What is the law of conservation of energy?
200
The boiler or furnace that used the greatest percentage of its energy to heat a house has this.
What is highest energy efficiency?
200
The brakes energy is not lost. It is captured and used to generate electricity which is used to charge a battery and later drive the car.
What is hybrid technolgy?
300
An x-ray is a form of this type of energy.
What is electromagnetic energy?
300
Mr. McCarthy picks up a book from the floor and places it on the top shelf. The book now has more of this.
What is potential energy?
300
A solar cell, also called a photo cell, changes energy from this form of energy to this from of energy.
What is electromagnetic to electrical energy?
300
This is an advantage of light-emitting diode.
What is that they convert almost all electrical energy into light?
300
In order to cool the turbines in a nuclear power plant, water is used. This water is returned to usually a lake or ocean located by the plant. This happens to the water by the plant.
What is thermal energy of the water is increased?
400
This type of energy is released when the nuclei of atoms are split.
What is nuclear energy? (fission)
400
This is when potential energy was shown during the rubber band activity.
What is when the rubber band was pulled back?
400
This facility changes nuclear energy into electrical energy.
What is a nuclear power plant?
400
During energy conversion, energy is usually lost in one or both of these forms.
What is heat and sound?
400
Identify at least 5 forms of energy listed in your science text book.
What are heat (thermal), sound, mechanical, chemical, nuclear, potential, kinetic, and electromagnetic?
500
Logs burn in a fire place; these are the forms of energy conversions that occur.
What is chemical (potential) to thermal, electromagnetic, and sound?
500
Four forms of energy Mr. McCarthy has by carrying a book across the room.
What are potential, kinetic, mechanical, and chemical?
500
This is where coal (chemical) is burned (thermal) to create steam (kinetic) to drive a turbine (mechanical) to generate electricity.
What is coal-fired electrical-generating plant?
500
The energy conversion of a lamp with an incandescent light bulb.
What is electrical to heat and light?
500
The quiet refrigerator is more of this than the loud refrigerator.
