TermDefinition
field a region of space that has a physical quantity at every point
force a push or a pull
friction force that opposes the sliding motion of two surfaces that are touching each other
gravity an attractive force between any two objects that depends on the masses of the objects and the distance between them
net force the sum of all of the forces acting on an object
weight the gravitational force exerted on an object
inertia the tendency of an object to resist any change in motion
Newton's 1st Law of motion an object moves at a constant velocity unless an unbalanced force acts on it
Newton's 2nd Law of motion an object's acceleration is in the same direction as the net force on the object and is equal to the net force exerted on it divided by its mass
Newton's 3rd Law of motion when one object exerts a force on a second object, the second objects exerts a force on the first that is equal in strength and opposite in direction
air resistance a friction-like force that opposes the motion of objects that move through the air
centripetal force a force exerted toward the center of a curved path
free fall the motion of an object who's only force is gravity. Falling without air resistance.
law of conservation of momentum if no external forces act on a group of objects, their total momentum does not change
terminal velocity the maximum speed an object will reach when falling through a substance, such as air

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.
