QuestionAnswer
Force A push or a pull
Friction Resists relative movement;contact
Electrical Attraction or repulsion due to elec. field;long range
Gravitational The pull of an ovject against another; long range
Magnetic The pulls of 2 objects; long range
Air resistence Particles in the air against objects; contact
Applied Pushing; contact
Tensional Pulling apart; contact
Normal Force Pushe object up; contact
Newton's 1st Law An object at rest remains at rest, and an object in motion stays at a constant velocity and in a straight line unless an unbalanced force acts upon it
Newton's 2nd Law The acc. of an object depends upon the mass and the force
Newton's 3rd Law If an object exerts another force on another object, the 2nd object exerts an equal force onto it
Equilibruim Net Force=0
Static Equilibrium not moving, net force=0
Static Friction Applied, doesn't move
Kinetic Equilibrium Moving at a constant velocity
Kinetic Friction Slow movement, opp direction
Inertia Resistance to change in the position of motion
Weight Measure of attraction of gravity

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.
