### science

constant speed that doesn't change
constant velocity when speed and direction do not change.
Formula for momentum p=mv
instantaneous speed when it represents a specific instant in time
Acceleration is not just a change in velocity it is how fast that change happens.
force a push or a pull acting on an object in a certain direction.
vector an arrow represents a force showing magnitude and direcrion
net force the combination of all forces acting on a object
equilibrium when all forces cancel each other out.
balance forces no acceleration no change in motion.
unbalance forces no acceleration no change in motion
Gravity natural forces of attraction between any two objects
weight gravitational force exerted on an object
inertai the resistance of an object to a change in the speed or the direction of its motion
newtons 1st law of motion an object will stay at rest an object in motion will stay at motion until an unbalanced force acts upon the objects
air resistance a.k.a ''drag'' force that air exerts on a moving object
air resistance depends on speed,surface area
list three examples of forces gravity,normal force,friction
what is the SI unit for force newtons
u need three things for motion what are they how are u moving,how far i are going,how long does it take to get there
what are the 5 big things? 1)use metric system 2)always start @ zero 3)decimal yes 4)lable with units 5)measure to the decimal place that is precise.
a stationary location or object to which you compare other locations or objects is? centripetal acceleration
not always a certain direction distance
needs to be a strait line displacement
overall length from starting point to ending point distance
commonly used when giving directions distance
a roller coaster's equals zero meters displacement
need to be a certain direction displacement

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
