Fields and Forces

QuestionAnswer
What is the charge of electrons? Negative
What is the charge of protons? Positive
What is the charge of neutrons? Neutral (no charge)
How do motors convert energy? From electrical to mechanical
How do generators convert energy? From mechanical to electrical
What is transferred during conduction? Electrons
What is the sudden flow of electrons between objects? Static discharge
What is conduction? Two objects with a different charge touch, and electrons are transferred
What is induction? An electrically charged object is brought near a neutral object. Parts of the neutral object become charged with static electricity
What is friction? Electrons are transferred when two neutral objects are rubbed together
What is a conductor? Material that allows electrically charged particles to easily flow through it
What is an insulator? Material that does not allow electrically charged particles to easily flow through it
What are things that make electromagnets stronger? More wire turns, greater voltage, adding dry cells, increasing the size of the iron core, lowering the temperature
What affects friction the most? The textures of the object and the surface
What two things affect gravitational force? Mass (greater mass = greater force) and distance (less distance between objects = greater force)
Mass vs. weight (compare Earth to the Moon) Mass is the same everywhere, but objects weigh less on the moon than on Earth due to the weaker gravitational pull on the moon
Like ________, opposites ________. Like repels, opposites attract
What is static electricity? The buildup of electric charge on an object

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.
