Displacement
Displacement is the change in an object's position from the origin. Displacement is a vector quantity, and thus has both magnitude and direction.
Displacement = (final position) - (initial position) = change in position
D = Xf -Xi
D = displacement
Xf = final position
Xi = initial position
ΔX = short form for change in position
let value of Xf = f and Xi = i
