Is a unit of?

Velocity

5

grams x miles/hr

 

Is a unit of?

Momentum

6

Describe the Slope

This is a medium constant negative slope.

7

Describe the velocity at E.

The velocity has decreased until it is amost zero.

8

Describe the Slope or Steepness.

Medium, Positive, and Constant Slope or Steepness.

9

Compare slopes at C and D.

Slopes at C and D are both large and negative.  The slope at D is larger.

10


In linear motion, the difference between

-55 mph

and

+55 mph

is?

Direction only

 

11


Linear Motion

Motion along a line

12

What would be the net force upon this object?

10 N to the left.

13

Describe the Slope of this graph

Begins with a large positive slope.

The slope gradually decreases until the slope is equal to zero.

14

Acceleration can mean....

Speeding up

Slowing down

or

Turning

 

(Basically, anything you could feel while you were in a car would indicate acceleration)

15

Gravitational Field Strength near the Earth's surface

9.8 newtons/kilogram

16

The amount of matter in an object.

Mass

17

Describe the position at D

Positive

18

Slope or Steepness at A is.....

The slope at A is large and negative

19

As you go along the curve from A to E, the slope

Decreases

It goes from large negative to zero.

20

Describe the Slope

This is a medium constant negative slope.

21

Velocity

Vector Quantity or not?

Vector Quantity

50 mph - North  has both magnitude (50) and direction (North).

So, its a vector or vector quantity.

22

m/s

 

Is a unit of?

Speed

23

As you go from A to D, the slope

Increases.

It goes from a slope of zero to a large negative slope.

24

Describe the Slope

Medium Slope

Negative Slope

Constant Slope

25

Compare slopes at A and B

Both slopes are large and negative.  A has a higher slope.

26

The slope at C is...

The slope at C is medium and positive

27

Describe the Steepness

Medium, Constant, Negative Steepness

28

Describe the Slope

The graph starts with a small positive slope.  The slope increases until point "c"  Then the slope begins to decrease.

The slope is positive at all times in this graph.

29

Describe the slope or steepness at B

Small negative slope

30

Compare slopes at C and D.

Slopes at C and D are both large and negative.  The slope at D is larger.
