Question

What are mean Velocity​

Answer 1

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north)

Velocity defines the direction of the movement of the body or the object. ... Velocity is the prime indicator of the position as well as the rapidity of the object. It can be defined as the distance covered by an object in unit time. Velocity can be defined as the displacement of the object in unit time.

mark me as brainliest

Answer 2

Explanation:

The time average of the velocity of a fluid at a fixed point , over a somewhat arbitrary time interval T counted from time t.

for ex .... the mean velocity of the u component is. the time average of any other quantity can be defined in this manner.
