Average velocity formula with examples

Velocity is defined as:”The rate of displacement of a body is called its velocity.”The velocity tells us not only the speed of a body but also the direction along which the body is moving.Velocity of a body is a vector quantity.It is equal to the displacement of a body in unit time.And is represented as:



SI unit of velocity is the same as speed i.e.,meter per second.

Uniform velocity

“A body has uniform velocity if it covers equal displacement in equal intervals of time however short the interval may be.”In equation( d=v t ) is the average velocity of of a body during time t .It is because the velocity of the body may be changing during the time interval t.However,in many cases the speed and direction of a body does not change .In such a case the body possesses uniform velocity.That is the velocity of a body during any interval of time has the same magnitude and direction.

Average velocity is the total displacement covered in any direction in total interval  of time.”or ratio of total displacement to time.
