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

12

In reference to a hypotenuse of R, what is the y-component equal to?

y=rsinθ
