vocab and formulas


normal formal when all forces are balanced and acceleration is zero
net force for every action force, there is an equal
g acceleration due to gravity
newton kg*m/s, unit of force
applied force push or pull to get something in motion
kinetic friction opposes motion and is what must be overcome to keep an object moving
inertia the tendency of an object to maintain its state of motion (at rest or moving with a constant velocity)
force of gravity the force of the earth or planet acting on a mass
static friction force opposes motion and is what must be overcome to start an object moving
mass measure in kg and is not affected by gravity
terminal velocity when weight and air resistance balance out for a falling object, it no longer accelerates and thus falls at a constant velocity for the rest of its fall
newtons 1st law objects remain at rest or moving at a constant velocity unless acted on by an unbalanced force
newtons 2nd law f=ma
newtons 3rd law for every action force, there is an equal and opposite reaction force
coefficient of fruition (μ) depends on the surface texture
equilibrium when all forces are balanced and acceleration is zero

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.
