. What is Velocity also write its formula


Best Answer

i. Velocity is defined as rate of change of displacement with time. Velocity is a vector quantity. SI unit of velocity is m/s.

ii. Average velocity is defined as the ratio of the total displacement covered to the total time taken.

iii. Just as distance is always greater than or equal to the magnitude of displacement, average speed is greater than or equal to the magnitude of average velocity. Average speed and the magnitude of average velocity are equal when particle is travelling in a straight line without change in direction.

iv. Average Velocity= Total Displacement/Total Time
