Answer 2

If an object moves relative to a reference frame—for example, if a professor moves to the right relative to a whiteboard, or a passenger moves toward the rear of an airplane—then the object’s position changes. This change in position is known as displacement. The word displacement implies that an object has moved, or has been displaced.

Displacement is defined to be the change in position of an object. It can be defined mathematically with the following equation:

\text{Displacement}=\Delta x=x_f-x_0Displacement=Δx=x
