Velocity However, velocity is a vector quantity because it takes into account magnitude and direction. Distance and Displacement Practice Calculate the distance and displacement in each of the following situations. The shortest distance from the initial position to the final position of the body is called the magnitude of the displacement. So the numerical value of speed and velocity is the same. it is a vector quantity, so, the 4meter east eliminates the 4meter west and the 2meter south. Distance is the magnitude of displacement between two positions. Ques. Displacement can be measured in any unit that measures distance but the SI unit is meters. Distance and displacement both require a source point to be measured from. As this is a calculation that measures distance, its standard unit is the meter (m).
