TermDefinition
Formula for speed Distance ———— Time
Scalar quantity Quantity that has magnitude only
Example of a scalar quantity Distance, speed
Vector quantity A quantity with magnitude and direction
Example of a vector quantity Velocity, acceleration
Velocity Speed in a given direction
Formula for velocity Displacement —————— Time
Speed Distance travelled per unit time
Displacement The direct distance between an objects previous and current positions E.g. I walked from A———10m———B. I meandered down the road, meaning the distance I travelled was 15 metres, but I was displaced 10 metres which is a straight line from A to B
Formula for displacement s = ut + 1/2 at^2
Acceleration Change in velocity over time
Formula for acceleration a = v - u —— t
Unit for acceleration ms^ -2
Unit for velocity ms^ -1
Unit for speed m/s
Unit for displacement m

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.
