Free-Body Diagram a simple model to understand systems of objects with any amount of applied force.
Net Force the sum of all forces acting on an object.
Newton's First Law states that an object in motion will stay in motion, and an object at rest will stay rest unless acted on by a force.
Inertia An objects ability to resist any change in motion.
Noncontact Force A force that one object can apply to another object without touching it.
Gravity An attractive force that exists between all objects that have mass.
Field A region on space that has a physical quantity at every point.
Weight The gravitational force exerted on an object.
Newton's 3rd Law When an object applies force on another object, the second object applies a force of the same strength on the first object but the force is on the opposite direction.
Force Pair The forces two objects apply to each other.
Normal Force The force that pushes perpendicular to an objects surface.

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.
