Vector \Vec"tor\, n. [L., a bearer, carrier. fr. vehere, vectum,
to carry.]
1. Same as {Radius vector}.
2. (Math.) A directed quantity, as a straight line, a force,
or a velocity. Vectors are said to be equal when their
directions are the same their magnitudes equal. Cf.
{Scalar}.
Note: In a triangle, either side is the vector sum of the
other two sides taken in proper order; the process
finding the vector sum of two or more vectors is vector
addition (see under {Addition}).
