8-2 Sci Chapter 2

Slope, Distance, Velocity, Time

The slope of a distance vs time graph is equal to speed
The slope of a speed vs time graph is equal to acceleration
What is the difference between average speed and instantaneous speed? Average speed is total distance divided by total time. Instantaneous speed is speed you have at a specific point on the journey.
What is the difference between speed and velocity? Speed is how fast you are going over a certain distance. Velocity is speed and direction.
What is the difference between acceleration and speed? Speed is distance over time. Acceleration is how much your speed changes over time
What type of acceleration is cruise control on a straight road? zero acceleration
What type of acceleration is applying brakes on a truck? deceleration
What type of acceleration is dropping a ball from the roof? acceleration (due to gravity)
What type of acceleration is a motorcycle parked in a parking log? zero acceleration
What type of acceleration is a car turning a sharp corner? acceleration
time = ? distance divided by velocity
distance = ? velocity multiplied by time
velocity (speed) = ? distance divided by time

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.
