the direction or course followed by an airplane, missile, or the like
A term used in matrix multiplication to describe a real number as opposed to a matrix
Sum of two vectors
A relationship that graphs as a straight line. This means y is changing at a constant enterval.
The number of degrees a regular polygon can be rotated to map onto itself.
a positive ________ or association means that, in general, as one variable increases, so does the other; when increases in one variable generally correspond to decreases in the other, the association is negative
Vectors have two
Process of determining components

Straight line across from side to side (length)
Path of a projectile
The difference between the greatest number and the least number in a set of data.

Where is your vector, Victor?
A triangle with one right angle.
Visual method of adding vectors. The resultant is the diagonal line across the parallelogram.
Head to Tail Method
When adding vectors, they should be added arrow head of one to the tail of the next. Scale and direction should be maintained.
The vector that is created when vectors are added or subtracted...the resulting vector
unit vector notation
describes vectors by breaking them into there x, y and z components and are denoted by "i-hat", "j-hat" and "k-hat"
Used in vector resolution to find the adjacent component of a vector
Used in vector resolution to find the opposite component of a vector
Used in combining component vectors to find the angle (direction) of the resultant vector
the process of breaking down a single vector into component vectors that are at right angle to each other.
the process of combining similar axial components using simple addition or subtraction. The components must be parallel.
