vector is a quantity that has both magnitude and direction
Acceleration is a measure of the change in velocity
force is a push or pull on an object
contact force is a push or pull on an object by another object that is touching it
newton's 2nd law the acceleration of an object equals the net force on the object divided by the objects mass
friction is a force that resists the sliding motion of two surfaces that are touching
free body diagram is a simple model to understand systems of objects with any amount of applied force
net force is the sum of all the forces acting on an object
newton's first law on object in motion will stay in motion and an object at rest will stay at rest unless acted on by a force

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.

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.
