Math definitions

bearing

angular direction measured from one position to another using geographical reference lines.

components

the horizontal and vertical aspects of a vector

direction

the course along which a vector moves

equal vectors

have same magnitude and direction; corresponding components will be equal

initial point

starting coordinates of a vector

magnitude

length of a vector

opposite vectors

have same magnitude but reversed directions

parallel vectors

have the same direction but not necessarily the same magnitude

resultant

the sum of the vectors acting on a particular object

standard position

vector whose initial point is at the origin

terminal point

ending coordinates of a vector

vector

a directed quantity requiring both magnitude and direction; represented by a line in a plane with an assigned direction

velocity

a vector quantity that is speed with a direction

zero vector

represents no displacement

scalar

a quantity determined solely by magnitude
