Introduction of Velocity and Acceleration (Distance and Displacement)

• Distance

        The distance covered by a moving body is the length of path covered by the body. In SI system,            distance is measured in metre (m). It is a scalar quantity as it has only magnitude but no direction. 

• Displacement

         The shortest distance covered by a moving body in a fixed direction is called displacement. In SI          system, it is measured in metre (m). Displacement is a vector quantity as It has both magnitude             and direction.
