motion

worddefenition
contact force when two objects hit or bump into each other (friction)
inertia objects want to resist motion (at rest stays at rest in motion stays in motion)
Action-at-a-distance force when two forces act on each other but don't touch or bump (gravity) (magnets repealing)
newtons 1 law Something at rest stays at rest and something in motion stays in motion (law of inertia)
newtons 2 law the force needed to move an object depends on mass and acceleration (when moving with more force it will go faster)
for every action there has to be a equal and opposite reaction
net force a combination of forces acting on a object
units for force newtons
units for acceleration M/S squared
formula for force F=ma
calculation of net force 1v+2v=3v same direction add different subtract

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.
