### Vector

9

## T/F Scalar quantities can be positive or negative.

### False. Scalar quantities are always positive.

10

## T/F Vector quantities can be positive or negative.

### True. Depends on which way you are going.

11

## Total length of path traveled

### Distance

12

## Distance is a _______________ value

### Scalar

13

## Distance is measured in ______________.

### Meters

14

## Total change in position; how far you end up from where you began

### Displacement

15

## Displacement is a __________ value

### Vector

16

## T/F Displacement can be positive or negative.

### True. Displacement is a vector value.

17

## Displacement is measured in __________.

### Meters

18

## 1 meter is equal to about how many feet?

### 3.3

19

## The rate at which distance is covered

### Speed

20

## Speed is a ________________ value

### Scalar

21

## T/F Speed can be either positive or negative.

### False. Speed is a scalar value. It is always positive.

22

## Speed and Velocity are both measured in what?

###
Meters/Second

23

## Average Speed (formula)

###
v=d/t

(Speed=total distance divided by total time)

24

## Speed of light

### 186,000 miles/second

25

## Distance traveled (formula)

###
d=vt

(Distance=speed x time)

26

## The rate of change in position, or the rate at which displacement is covered.

### Velocity

27

## Velocity is a _____________ quantity.

### Vector

28

## T/F: Velocity must be positive.

### False. Velocity is a vector quantity, so it can be positive or negative, depending on which way you move.

29

## Velocity is based on what?

### Displacement over time
