IB Physics Vocab

Section: Electrostatics

TermDefinition
Law of Conservation of Charge The total electric charge of an isolated system remains constant.
Conductor material through with electric charge flows freely
Insulator material through which electric charge does not flow freely
Coulomb’s Law The electric force between two point charges is directly proportional to the product of the two charges and inversely proportional to square of the distance between them, and directed along the line joining the two charges. (F = k q1 q2 / r2)
Insulator material through which electric charge does not flow freely
Electric Field Strength (E) Electric force per positive unit test charge (E = F/q)
Radial Field field that extends radially (like the electric field around a point charge or the gravitational field around a planet)
Electric Potential (V) work done per unit charge moving a small positive test charge in from infinity to a point in an electric field. (V = W/q) (V = kq/r) (NOTE: the work done is path independent)
Electric Potential Energy (Ee) energy that a charge has due to its position in an electric field

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.
