Newton A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second
Net Force The overall force on an object when all the individual forces acting on it are adding together
Unbalanced Forces Forces that produce a nonzero net force, which changes an objects motion
Balanced Forces Equal forces acting on an object in opposite directions
Friction The force that one surface exerts on another when the two surfaces rub against each other
Static Friction Friction that acts on objects that are not moving
Sliding Friction Friction that occurs when one solid surface slides over another
Rolling Friction Friction that occurs when one object rolls over a surface
Fluid Friction Friction that occurs as an object moves through a liquid
Gravity The force that pulls objects towards each other
Mass A measure of how much matter is in an object
Weight A measure of the force of gravity on an object
Free Fall The motion of a falling object when the only force acting on it is gravity
Air Resistance The fluid friction experienced by objects falling through the air
Projectile An object that is thrown
Compression The part of a longitudinal wave where the particles of a medium are close together
Tension Stress that stretches rock so that it becomes shinier in the middle
Inertia The tendency of an object to resist any change in its motion
Momentum The product of an object's mass and velocity
Law of Conservation of Momentum The rule that in the absence of outside forces the total momentum of objects that interact does not change
Satellite Any object that orbits around another object in space
Centripetal Force A force that causes an object to move in a circle

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.
