Displacement

The displacement of an object is defined as the vector distance from some initial point to a final point. This change in position is known as displacement. The word “displacement” implies that an object has moved, or has been displaced.

It is therefore distinctly different from the distance traveled except in the case of straight-line motion in one direction. The distance traveled divided by the time is called the speed, while the displacement divided by the time defines the average velocity. Displacement is defined as follow:

\[\Delta x=x_f−x_0\]

where \(\Delta x\) is displacement, \(x_f\) is the final position, and \(x_0\) is the initial position. Displacement has a direction as well as a magnitude!
