CHAPTER 32 YEAH

QuestionAnswer
the study of electric charges at rest electrostatics
a force that one charge exerts on an other. when the charges are the same sign, they repel' when the charges are opposite, they attract electrical force
the fundamental electrical property to which the mutual attractions or repulsions between electrons or protons is attributed charge
the principle that net electric charge is neither created nor destroyed but is transferable from one material to another conservation of charge
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's law
SI unit of charge, one coulomb (symbol C) is equal to the total charge of 6.24 x 10^18 electrons coulomb
material, usually a metal, through which electric charge can flow. Good conductors of heat are generally good charge conductors conductor
a material that is a poor conductor of electricity insulator
material that can be made to behave as either a conductor or an insulator of electricity semiconductor
term applied to electric charge that has been redistributed on an object because of the presence of a charged object nearby induced
term applied to a voltage, electric field, or magnetic field that s created due to a change in or motion through a magnetic field that is created due to a change in or motion through a magnetic field or electric field. induced
the charging of an object without direct contact. see also electromagnetic induction induction
allowing charges to move freely along a connection between a conductor and the ground grounding
term applied to an atom or molecule in which the charges are aligned so that one side is slightly more positive or negative than the opposite side electrically polarized

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.
