Physics

Equations

TermEquation
s dissstance
d displacement
formula for velocity = displacement over time
formula for acceleration = velocity over time
vector quantity any quantity that has magnitude and direction, such as displacement or velocity.
scalar quantity quantities that can be communicated and used only by defining their value and units.
Position-time graph has length traveled along y-axis, time along x, slope of = velocity
velocity-time graph has velocity along y-axis, time along x, slope of = acceleration
speed and velocity can be the same if... they're in the same direction
formula for speed = distance over time
VECTOR OR NOT? d = m/v scalar
VECTOR OR NOT? v = d/t vector
VECTOR OR NOT? s=s/t scalar
VECTOR OR NOT? f = ma vector
vector... velocity + displacement
scalar... speed + distance
kinematics DESCRIPTION of how movement happens
dynamics CAUSES of motion
mechanics study of motion
average speed vs instantaneous speed? Average speed is the total path taken by an object divided by the total time. Instantaneous speed is the speed recorded at a specific time or instant.
When is displacement = distance? when they go one way and don't double-track

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.
