The displacement vector d from P1 to P2 may be written as d = (x2 - x1)i + (y2 - y1)j. The displacement d is (x2 - x1) units in the x-direction plus (y2 - y1) units in the y-direction. The magnitude of the displacement is d = ((x2 - x1)2 + (y2 - y1)2)½.

The trajectory has horizontal (x) and vertical (y) components. Velocity is a vector (it has magnitude and direction), so the overall velocity of an object can be found with vector addition of the x and y components: v2 = vx2 + vy2. The units to express the horizontal and vertical distances are meters (m).

Suppose that the coordinates of the vector are (3, 4). You can find the angle theta as the tan–1(4/3) = 53 degrees. So if you have a vector given by the coordinates (3, 4), its magnitude is 5, and its angle is 53 degrees.
