- scalar:A quantity, such as mass, length, or speed, that is completely specified by its magnitude and has no
direction. - vector:A quantity possessing both magnitude and direction, represented by an arrow the direction ofwhich
indicates the direction of the quantity and the length of which is proportional to the magnitude. - vector addition:The process of finding one vector that is equivalent to the result of the successive application
of two or more given vectors.
