What are the horizontal and vertical parts of vectors called

A 2-dimensional vector may be expressed by

A = Ax i + Ay j

where i and j are unit vectors along the x (horizontal) and y (vertical) axes respectively.

Ax = horizontal part (x-component)

Ay = vertical part (y-component)

Alternatively, the vector may be written as

A = (Ax, Ay)

Answer:

Horizontal part = x-component

Vertical part = y-component
