Type of energy that depends on the speed of molecules.
What is thermal or heat energy
300
Explain the transformation of a book falling from table.
What is Potential to kinetic to thermal
300
When you drop a book on the floor, what happens to its original potential energy?
What is the potential energy was transfered to kinetic and thermal energy
300
Wind energy, coal energy, nuclear energy, ethonal energy, hydroelectric energy and solar energy all are used to make electricity. However, solar energy is different, what do all the other energy sources do that solar energy does not?
What is Turn a turbine that turns a generator to make electricity.
300
A device that transforms kinetic energy into electrical energy.
What is a turbine (generator)
400
Type of energy that depends on the flow of electrons
What is electrical energy
400
Explain the transformation of energy that occurs in a coal burning power plant. List the type of enrgery and where it comes from.
What is Chemical to thermal to kinetic to kinetic to electrical
400
Most forms of _______ can be _______ into other forms
What is (1) energy (2) transformed
400
Explain hydroelectric energy and give one advantage and one disadvantage.
What is hydroelectric energy is using the potential energy of water and turning it into electrical energy. One advantage is it does not pollute. One disadvantage is that it disrupts aquatic life.
400
State the Law of Conservation of Energy
What is Energy can not be created of destroyed it can only be transfered or tranformed.
500
Type of energy stored in bonds
What is Chemical energy
500
Explain the transformation that takes place to make a toaster work using a wind turbine. Begin with the sun.
What is thermal energy to kinetic energy to kinetic energy to electrical to thermal to radiant
500
When you drop a tennis ball, it hits the floor and bounces back up. But, it does not reach the same height as before and each time bounce is smaller than the previous one. However, you notice the tennis ball is slightly warmer after it finishes bouncing. Explain how the law of conservation of energy is obeyed.
What is During each bounce, some of the kinetic energy of the ball in transfered into thermal energy. As a result, energy is not created or destroyed, but only changes form so that the law of conservation of energy is obeyed.
500
Explain how nuclear energy is used to create electricity and give one advantage and one disadvantage.
What is Uranium atoms are split and heat is released to boil water. The boiling water creates steam. The steam turns a turbine and the turbine tunrs a generator, which makes a flow of electrons. One advantage is that is does not pollute the air. One disadvantage is that is makes radioactive waste.
500
