TermDefinition
Energy The ability to cause change
Kinetic Energy energy due to motion
Potential energy stored energy due to the interactions between objects and particles
Work The transfer of energy that occurs when a force is applied over a distance
Mechanical energy the total energy of an object or group of objects due to large scale motions and interactions
Sound energy the energy that sound carries
thermal energy energy due to motion of particles that make up an object
electric energy the energy that an electric current carries
radiant energy the energy the electromagnetic waves carry
nuclear energy energy that is stored in the nucleus of an atom
Law of conservation of energy energy can be transformed form one another of transferred from one region to another, but energy cannot be created or destroyed
Friction a force that resists the sliding of two surfaces that are touching
temperature represents the average kinetic energy of the particles that make a material
Heat the movement of the thermal energy from a warmer object to a cooler object
Wave a disturbance that transfers energy form one place to another without transferring matter
Mechanical wave a wave that can only travel through matter
Medium a materiel in which a wave travels
Transverse wave a wave in which the disturbance is perpendicular to the direction the wave travels
Crest the highest points on a transverse wave
Trough the lowest points on a transverse wave
Longitudinal wave a wave in which the disturbance is parallel to the direction the wave travels
Compressions the regions of a longitudinal wave where the particles in the medium are close together
Rarefactions the regions of a longitudinal wave where the particles are farthest apart
Electromagnetic waves a wave that can travel through empty space and through matter
Amplitude the maximum distance that the wave moves from its rest position.
Wavelength the distance from one point to the same point on the next wave
Frequency the number of wavelengths that pass a point each second

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.
