Energy

QuestionAnswer
Energy The ability to do work.
Potential Energy Energy that is stored.
Kinetic Energy Energy that is in motion.
Law of Conservation of Energy Energy can be neither created nor destroyed. It is transferred from one form to another.
Gravitational potential energy Potential energy based by the weight and height of an object. GPE = Weight times height.
Thermal Energy All the kinetic energy due to the motion of particles in an object (Heat)
Chemical Energy Energy of a compound that changes as its atoms are rearranged (Food, Battery)
Electrical Energy Energy of moving electrons.
Sound Energy Energy caused by an object's vibrations.
Light Energy (Radiant) Energy formed by electromagnetic waves. Energy that can be seen.
Nuclear Energy Energy produced by changes in the nucleus.
Conduction Transfer of thermal energy by direct contact. (Jiffy Pop, pot on a stove)
Convection Transfer of thermal energy by circulation or movement of air or liquids. (Hot air popper, boiling water)
Radiation Transfer of thermal energy by electromagnetic waves. (Microwave, light)
Thermal Conductor Material through with energy can be transferred easily (steel, copper)
Thermal Insulator Material that reduces or prevents the transfer of heat (wood, Styrofoam)
Joule Standard unit of energy.
Elastic Potential Energy Energy stored in elastic (rubber band)
Celsius Standard unit used for temperature where freezing is 0 degrees and boiling is 100 degrees.
Fahrenheit Unit of measuring temperature where freezing is 32 degrees and boiling is 212 degrees.
Kelvin A scale of temperature beginning at absolute zero (−273.15°C or −459.67°F).
Temperature a measure of the average kinetic energy of the particles in an object
Mechanical Energy potential plus kinetic energy
Heat the energy transferred between objects that are at different temperatures
Absolute zero the temperature at which molecular motion stops ( 0 Kelvin)

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.
