Position-time graphs

TermDefinition
To determine how far from the detector an object is located look at the vertical axis of the position-time graph
To determine how fast an object is moving look at the steepness (i.e. the slope) of the position-time graph
To determine instantaneous speed from a curved position-time graph take the slope of a tangent line
To determine which way the object is moving look at which way the position-time graph is sloped
A position-time slope like a front slash / means means the object is moving away from the detector
A position-time slope like a back slash \ means means the object is moving toward the detector
Concave up, a U shape means indicates a positive acceleration
Concave down, a frown means indicates a negative acceleration

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.
