    Displacement and Velocity are both concepts of motion and an object is said to be in motion if it changes its position with time. Displacement is the shortest distance from the initial to the final position of the object, which is not the same as distance travelled because it is the length of an imaginary straight path. Displacement is measured in units of length, such as meters.
