Practice Questions on Directions of a Vector
Q1: Find the direction of the vector for the initial point (12, 3) and final point (5, 9).
Q2: Find the horizontal displacement if the direction of the vector is 60° and the vertical displacement is 12.
Q3: Find the direction of the vector for the initial point (2, -3) and final point (-11, 0).
Q4: Find the direction of the vector if vertical displacement is 9 and horizontal displacement is 12.
Direction of a Vector Formula
A vector is formed when two distinct points are joined with each other. The point from which a line was drawn to the other point determines the direction of that vector. A vector’s direction is the angle formed by the vector with the horizontal axis, also known as the X-axis. It is provided by the counterclockwise rotation of the vector’s angle about its tail due east. In other words, the orientation of a vector, that is, the angle it makes with the x-axis, is defined as its direction.
