mechanical energy the total energy of motion and position/stored energy of an object
chemical energy the potential energy stored in chemical bonds
Gravitational Potential Energy the potential energy of an object due to its position/height above the ground.
light energy energy that travels in the form of electromagnetic waves
sound energy the energy of vibrating matter.
electrical energy the energy of moving electric charges.
thermal energy the energy of moving particles
nuclear energy the energy stored in the nucleus of an atom.

Convection The process of thermal energy transfer in fluids (gases and liquids) through rising and falling currents in the fluid.
Radiation The transfer of energy through matter or space by electromagnetic waves.
Conductor A material that can easily transfer thermal energy.
Insulator A material that does not readily transfer thermal energy.

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.
