Scalar vs Vector
What is vector quantity
A vector quantity has both magnitude and direction.
Resultant of 3 units right and 4 units right:
7 units right
What is the magnitude of a vector
The length or size of the vector
How do we communicate the direction of a vector?
Angles, or unit vector notation in a particular coordinate system
Give an example of a vector quantity
Example include velocity, displacement, force.
