Chapter 2&5 JP

Energy and energy resources

States that energy can change its form but is never created or destroyed Law of conservation of energy
A device that transforms kinetic energy into electrical energy Generator
A set of steam powered fan blades that spin a generator at a power plant Turbine
Energy source that has replenished continually Renewable source
Energy resource that is used up much faster than it can be replaced Non-renewable source
Energy source that can't be used up by humans Inexhaustible resource
New renewable or inexhaustible energy source; includes solar energy, wind, and geothermal energy. Alternative source
Device that transforms radiant energy directly into electrical energy Photovoltaic
Photovoltaic Basically a solar panel
Inexhaustible source Energy we won't run out of (example is wind)
Alternative resource A way of making energy without burning oil, gas,coal
Nonrenewable resource Energy that we use faster than it is made (example is oil or gas)
Renewable resource Energy that we shouldn't run out of
Turbine The part of the generator that spins (Think of the blades on a windmill)
Generator A tool that changes energy of motion into electrical energy
Law of conservation of energy Energy is never made or lost – it just changes form
Transformation Changing something in someway or shape
Nuclear energy Energy contained in atomic nuclei
Electrical energy Energy carried by electric current
Chemical energy Energy stored in chemical bonds
Energy The ability to cause change
Mass Amount of particles in an object
Thermal energy Total kinetic and potential energy
Potential energy Stored energy
Kinetic energy Energy of motion
What is an example of kinetic energy? Finish Skateboarding down hill Or start uphill
What is an example of potential energy? The very height of the energy like a bicycle at the top of the hill
What is an example of transformation? What is a caterpillar turning into a butterfly
What are two examples of Electrical energy? Lightning, plug into electrical outlets
Energy and object has due to its motion Kinetic
Energy stored in an object due to its position Potential
The sum of the kinetic and potential energy of the particles in a material Thermal
A measure of the amount of matter in an object Mass

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
