![]() ![]() Average Velocity: The average velocity of a particle for a given interval of time is defined as the ratio of its displacement to the time taken.Īverage velocity is independent of path taken between any two points.In calculus notation, this limit is called the derivative of r with respect to time, written as dr/dt If the position of a particle changes by △r in a small time interval △t, the limiting value of △r/△tĪs △t approaches zero, gives the instantaneous velocity. ![]() It is defined as rate of change of particle position with time. Instantaneous Velocity: Instantaneous velocity of a particle is velocity at a particular instant of time.It is defined as the rate of change in displacement with respect to time. If a partial travels equal interval of distance of speeds v 1, v 2, v 3 ….v n respectively, thenĪverage speed is harmonic mean of individual speeds. If a particle travels distances S 1, S 2, S 3….etc in time t 1, t 2, t 3 …etc, respectively. Average Speed: The average speed of a particle is defined as ratio of total distance travelled to the total time taken.In calculus notation, this limit is called the derivative of s with respect to time, written as ds/dt △S is the distance travelled by a particle in a time interval △t, then instantaneous speed is the limiting value of △S/△t as △t approaches zero. Instantaneous speed of a particle is speed at a particular instant of time. Speed : It is defined as the rate of change of distance, with respect to time.
