What is Kinetic Energy
100
Explain the transformation that takes place when you rub your hands together. START FROM THE SUN GIVING US FOOD FOR ENERGY ( 5 steps)
What is 1. light energy( from the sun) to 2. chemcial energy (plants make sugar) to 3. chemical (stored in bonds in food) to 4. kinetic (movement of the hands) to 5. thermal (heat produced from friction)
100
Renewable or nonrenewable: wind energy
What renewable
100
Moving wind turbines convert _________________ energy into electrical energy.
What is kinetic
100
True or false: Energy can not be created of destroyed it can only be transferred or transformed.
True
200
The type of Energy that depends on mass and position
What is potential energy
200
Explain the transformation that takes place when you turn on a flashlight. From the battery to the light. 4 steps
What is 1. Chemical (of the battery) to 2. electrical (flow of elctrons) to 3. radiant (of the light) to 4. thermal ( the heat produced by the light)
200
Renewable or non: Sun
What is renewable?
200
Hydroelectricity can generate electricity because of the _______________________ energy of the water.
What is kinetic
200
An energy resource that is used up faster that is can be replaced. It takes a long time to replace.
What is a nonrenewable resource
300
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. Explain the type of energy and where it comes from. 3 steps
What is 1. Potential ( due to the position of the book) to 2. kinetic ( motion of the book) to 3. thermal ( the friciton between the book and the air)
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
Coal, ethanol, and propane energy have this in common.
What are three examples of chemical energy?
300
The definition of an energy resource that is replenished continually or in a short amount of time.
What is renewable resource
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 enrgy and where it comes from. 5 steps
What is Chemical (coal) to thermal (heat released from breaking the bonds of coal to boil water)to kinetic ( the steam makes) to kinetic (turbine move) to electrical (the turbine is conected to a generator that make a flow of electrons)
400
Renewable or non: Oil
What is nonrenewable
400
List three fossil fuel energy sources and give one advantage and disadvantage of fossil fuels.
Coal, petroleum, propane (ethanol is NOT) One advantage is that they generate power efficiently. One disadvantage is that they pollute and are nonrenewable.
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 in molecules of substances
What is Chemical energy
500
Explain the transformation that takes place to make a toaster work using a wind turbine. Begin with the sun. (6 steps)
What is thermal energy (from the sun) to kinetic energy (of the wind) to kinetitc energy (the blades to spining) to electrical ( the turbine turns a generator and makes a flow of electons) to thermal ( heat from the toster) to radiant ( when the toaster get hot enough it will emit light)
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 energy transformation has occured.
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 hydroelectric energy and give one advantage and one disadvantage.
What is hydroelectric energy is using the mechanical energy of water and turning it into electrical energy. One advantage is it does not pollute. One disadvantage is that it disrupts aquatic life.
