Displacement of an object is the change in the position of the particle in certain direction. Displacement is measured using the units of length same as that position coordinate measured in the units of length. In general, we can say that displacement is a shortest distance between two points. The figure given in the next section will explain the correct picture of this physical quantity.
By definition, displacement is the minimum distance or the shortest distance between two points. It has a proper direction and magnitude. Displacement can be positive or negative. When a body is in a circular motion, the displacement become angular displacement. The rate of change of displacement will give the velocity of that object.
