Flashcards in Vectors Deck (12):

1

## What is an Inertial Frame of Reference?

###
Frame of Reference moving with constant velocity relative to origin;

impossible to tell whether FOR is in motion if observer is moving too

2

## What is a Vector?

### A directed line segment |R|

3

## What is a Vector Quantity?

### Measurements that have both magnitude (size) and direction (negative/positive)

4

## What are examples of a vector quantity?

### Force, Velocity, Weight, and Displacement

5

## What is a Scalar Quantity?

### Measurements with only magnitude

6

## What are examples of a scalar quantity?

### Mass, Distance, Speed, and Energy

7

## What is a Resultant?

### A vector sum; vectors add constructively from head to tail

8

## What is a Concurrent Vector?

### Vectors that act at the same place and same time

9

## What is a Equilibrant?

### A third vector that is equal and opposite to the resultant

10

##
What is a Frame of Reference?

### Observer's POV relative to the location of object; requires coordinate grid with origin

11

## In reference to a hypotenuse of R, what is an x-component equal to?

### x=rcosθ
