Chap 3 - Vectors Flashcards
magnitude of acceleration
a vector can be broken down into two perpendicular __________.
components
How do you pronounce this?
“eye hat”
Displacement vector
Volume
(vector or scaler)
Scaler
the length of a unit vector is
1
How would you say this?
The velocity is equal to the displacement divided by the change in time.
(It would be incorrect to say “change in displacement” or to just say “time”)
Weight
(vector or scaler)
Vector
(weight is a force)
(the direction of weight is pretty much straight down)
Scaler quantity
Has a size (magnitude) only
The y-component of acceleration
Magnitude
How large or small something is
Temperature
(vector or scaler)
Scaler
How do you pronounce this?
“jay hat”
Mass
(vector or scaler)
Scaler
Acceleration
(vector or scaler)
Vector
the unit vector in the x-direction
(eye hat)
Position
(vector or scaler)
Vector
vector quantity
Has both size and direction.
the unit vector in the y-direction
(jay hat)
Distance
(vector or scaler)
Scaler
Adding two vectors by adding their components is called __________.
Algebraic addition of vectors.
The sum of two vectors is called the ________
Resultant
The component of velocity in the y-direction
acceleration vector
Speed
(vector or scaler)
Scaler
multiplying a vector by “-1” will…
reverse its direction
This will shrink or stretch a vector
multiplying by a scaler
Position vector
(different than the displacement vector)
The component of velocity in the x-direction
Time
(vector or scaler)
Scaler
Force
(vector or scaler)
Vector
breaking a vector down into components is called ___________.
vector decomposition
A quantity that has both magnitude and direction
Vector
The x-component of acceleration
Displacement
(vector or scaler)
Vector
The magnitude of a vector is a _________.
Scaler
Magnitude of the velocity
velocity vector
Velocity
(vector or scaler)
Vector
