Velocity: The changes happen in position is called velocity. Velocity is considered as the physical quantity. The magnitude and direction are necessary for this velocity.

The formula for velocity is,

`v=d/t`

Here, the displacement is denoted as d and the time of the displacement is denoted as t.

Velocity = change in position over a specific time interval

v= (xf - xo)/(tf - to)

where xf is the final position and xo is the initial position.

where tf is the final time and to is the initial time.
