Energy of Motion
What is Kinetic Energy
100
Explain the transformation that takes place when you rub your hands together. START FROM THE SUN ( 5 steps)
What is light energy( from the sun) to chemcial energy (plants make sugar) to chemical (stored in bonds in food) to kineitc (movement of the hands) to thermal (heat produced from friciton)
100
True or False - Thermal energy is transferred from hotter objects to cooler objects.
True
100
Wind turbines convert _________________ energy into eletrical energy.
What is kinetic
100
What is a renewable resource
An energy source that is always available because it doesn't get used up.
200
Energy that is stored
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 Chemical (of the battery) to electrical (flow of elctrons) to radient (of the light) to thermal ( the heat produced by the light)
200
True or False - Energy transfer by radiation is much faster than by conduction or convection.
True
200
Hydroelectricity can generate electricity because of the initial _______________________ energy of the water.
What is potential
200
An energy source that is used up faster that is can be replaced. (not an example)
What is a nonrenewable resource
300
Energy passed through convection, conduction and radiation
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 Potential ( due to the position of the book) to kinetic ( motion of the book) to 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 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
Energy that is passed through electrons moving
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
Why is the bottom of saucepans often made of copper?
Because it conducts heat better than other metals.
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. Found in batteries and the digestive system
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 kineitc energy (the baldes to spining) to electrical ( the turbine turns a generator and makes a flow of electons) to thermal ( heat from the toster) to radient ( when the toaster get hot enough it will emmit light)
500
Is energy that is stored in an object visible?
No
500
List an object that does the following energy transformations - a) electrical energy to sound energy b) electrical energy to thermal energy c) electrical energy to light energy d) electrical energy to kinetic energy
a) An MP3 player b) A heater or oven c) A light bulb d) An electric car or CD player
500
Name Each type of energy and give an example.
Kinetic, Potential, Light, Heat, Chemical, Nuclear, and electrical
