What is a scalar quantity? Quantity that has a number and unit. E.g., 10 m
What is a vector? Quantity that has a number,a unit and a direction. E.g., 24 m/s [W]
Define position Distance and direction of an object from a reference position. Vector.
Define displacement Change in position of an object. Vector quantity.
Formula for displacement? Final position minus initial position.
Define speed Ratio of distance travelled to the total time time of travel. Scalar.
Formula for speed Distance travelled divided by the time.
Define velocity Ratio of displacement to the time interval for displacement. Vector.
Formula for velocity Displacement divided by the time.
Define accelerated motion Motion with changing velocity (changing speed, changing direction, or both changing speed & direction).
Define constant acceleration Straight line motion in which velocity changes by same amount each second
Formula for acceleration Change in velocity (final velocity minus initial velocity) divided by time. Vector.
State value of acceleration due to gravity 9.8 m/s^2 [down]

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.
