Chapter 8-9

QuestionAnswer
What is the study of motion called? Kinematics
What is a scalar? A scalar describes the 'size' of a measurement. (not the direction)
What is the term used to describe the magnitude/size and direction? Vector
-Bob runs 8m/s- This is an example of a scalar or a vector? Scalar
-Zoe runs 300m east- This is an example of a scalar or a vector? Vector
What is the term to describe the length between 2 points is? Distance (scalar)
What is the term to describe a specific point with respect to a reference point? Position (vector)
What is displacement? This is how far the final position is from the initial position. (vector) ex) Rob ran a 200m relay around the track. - Distance = 200m - Displacement = 0m
-Fill in the blank- When calculating direction we use negative and positive numbers. Right, up forward, north, and east are all examples the number would be _________. Positive
-Fill in the blank- When calculating direction we use negative and positive numbers. Left, down backward, south, and west are all signs the number would be __________. Negative
Time is how long it takes an event to occur. What is this measured in? Seconds (scalar)
What is uniform motion? When an object moves at a constant speed in a straight line.
What is the term to describe the distance traveled divided by the time taken to travel? Speed ex) 80 km/h or 11m/s
What is the term to describe the displacement traveled divided by the time taken? Velocity
What is the term to describe the point when 2 lines that cross over? Intercept
How do you calculate slope? M= Rise/Run -> on a position time graph this is used to find velocity
How do you convert 97.3km/h to m/s? 97.3 km/h / 3.6 = 27.02 m/s
How do you convert 43.8 m/s to km/h? 43.8m/s x 3.6 = 157.68 km/h
What is the term to describe the rate at which velocity changes? Acceleration (vector) -WOOT WOOT, Chapter 9!-
Acceleration depends on 2 variables what are they? 1. Time it takes to speed up or slowdown 2. How much the velocity changes
Is it possible to have a negative acceleration? Yes.
2 ways of calculating Acceleration, one is given to you on your cheat sheet, what is the other way? The slope of a v/t graph
-Fill in the blank- ________ is whenever gravity is the only force on a object. Freefall
In freefall ALL objects accelerate at what rate? -9.80m/s 2 or 9.80m/s (down) - Gravity is always downward this means is always negative

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.
