Distance is the actual path length covered by a moving particle of body in a given time interval while displacement is the change in position vector i.e. a vector joining initial to final positions.
Example: A particle was moving in a semicircle from point A to B which are two oppisite side of a semicircle then the distance cover is Pi R while the displacement will be 2R
The average speed of a particle in a given interval of time is defined as the ratio of distance travel to the time taken while average velocity is defined as the ratio of displacement to time taken if the distance travelled is S and displacement of a particle is R in a given time interval "t" then average velocity is R/t.
The main difference between speed and velocity is speed don't have any directions while velocity have direction.
The rate of change of velocity in a particular time interval is known as acceleration.
