WebbThe 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_0 Displacement = Δx = xf − x0. x_f xf refers to the value of the final position.
