Electrostatics The study of electric charges at rest.
Electrical Forces A force that one charge exerts on an other. When the charges are the same sign, they repel; when the charges are the opposite, they attract.
Charge The fundamental electrical property to which the mutual attractions or repulsions between electrons or protons is attributed.
Conservation of Charge The principle that net electric charge is niether created nor destroyed but is transferable from one material to another.
Coulomb's Law The relationship among electrical force, charges, and distance: The electrical force between two charges varies directly as the product of the charges and inversely as the square of the distance between them.
Coulomb SI unit of charge. One coulomb (symbol C) is equal to the total charge of 6.24 x 10 to the power of 18 electrons.
Conductor (a) Material through which heat can be transferred. (b) Material, usually a metal, through which electric charge can flow. Good conductors of heat are generally good charge conductors.
Insulator (a) A material that is a poor conductor of heat and that delays the transfer of heat. (b) A material that is a poor conductor of electricity.
Semiconductor Material that can be made to behave as either a conductor or an insulator of electricity.
Induced (a)Term applied to electric charge that's been redistributed on object bc presence of charged object nearby. (b)Term applied to voltage, electric field, or magnetic field that's created due to change in or motion through magnetic field or electric field.
Induction The charging of an object without direct contact.
Grounding Allowing charges to move freely along a connection between a conductor and the ground.
Electrically Polarized Term applied to an atom or molocule in which the charges are aligned so that one side is slightly more positive or negative than the opposite side.

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.
