What is the difference between velocity and average velocity?
Asked by | 25 Apr, 2012, 10:36: PM
answered-by-expert Expert Answer
Average velocity is calculated over a period of time. For instance, let's say the initial position is zero meters. The final position is twenty meters. If it took five seconds to travel twenty meters, then the average velocity is four meters per second.

Instantaneous velocity is calculated at an instance of time. An example would be calculating the velocity at twenty-one meters at a time of exactly three seconds. Theinstantaneous velocity would be seven meters per second
