# Energy and Matter

### Interactions of Energy and Matter

TermDefinition
Energy transformation The process of changing energy from one form to another
Thermal Energy Energy that is generated by a source and measured by heat
Conduction The movement of heat or electricity through matter
Convection The transfer of thermal energy through a fluid (gas or liquid)
Radiation Energy transmitted in waves or a stream of particles
Magnetic Forces The attractive and repulsive forces between two poles
Electric Forces Occur when ions create attractive and repulsive forces
Electromagnetism A force combining both electric and magnetic forces
Conductor material that transfers energy quickly.
Insulator material that does not transfer energy easily
Electricity is the flow of an electric charge
Electrical Current the flow of electrical energy in a circuit.
Circuit a loop of materials that allows an electrical current to flow. It has no beginning or end
Load (Circuits) The device that changes the electrical energy into another form of energy like light, sound, heat, or motion
Open Circuit The path is incomplete. Electrical current will not flow through the circuit
Closed Circuit The path is complete. Electrical current flows through the circuit
Complete Circuit an uninterrupted path for electrons to flow from an energy source (i.e. battery or household power), through a device and back to the source
Series Circuit all components are connected end-to-end to form a single path for current flow.
Parallel Circuit an electrical path that branches so that the current divides and only part of it flows through any branch.
Electric Field the area around an electric charge that experiences the force exerted by the electric charge
Generator an electric machine that converts mechanical energy into electrical energy
Static Electricity a stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair.
Electrons Negatively charged subatomic particle
Induction The process of generating current in a conductor by placing it in a changing magnetic field
Friction a force, the resistance of motion when one object rubs against another

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
