Speed is a matter of how fast an object is moving regardless of the direction it's going, whereas velocity is a matter of how fast an object gets somewhere with respect to direction.
Velocity is a measure of how quickly an object moves. So, the velocity is the change in the position of an object, divided by the time. Velocity has a magnitude (a value) and a direction. The unit for velocity is meters per second (m/s).
v= ( Xf - Xi ) / t
v = velocity (m/s)
xf = the final position (m)
xi = the initial position (m)
t = the time in which the change occurs (s)
Δx = short form for "the change in" position (m)0Modal content

there are two formula for velocity .Eventually one can be derived from the other .
the first formula is : s = u + v t
the second formula is V^2 = U^2 + 2as
v= final velocity
u = initial velocity0Modal content

Velocity can be thought of as speed with direction. The formula for speed is change in distance divided by change in time. The formula for velocity is change in displacement divided by change in time. therefore velocity= s/t. where s= displacement and t= time. the unit of velocity id metre per second.0Modal content

Velocity=(Displacement)/(Time)
Unit:m/s0Modal content

velocity is displacement by time0Modal content

v=d/t.
where d is displacement
and tis a time.0Modal content

The formula is v=displacement/time S.I Unit is m/s0Modal content

The formula for velocity, which is a vector quantity having both magnitude and direction, is given by,
velocity = displacement / time
It has unit m/s.0Modal content
-
Velocity is a vector quantity. Hence it has direction as well as magnitude.
In order to calculate velocity we use the formula
Velocity = Displacement / Time
It has the Unit m/s.

Let us first understand the term velocity, according to techtarget.com, "Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s)"
Ahgg! so much technical, let me break the definition in parts.
- Velocity is something, "The distance traveled by a body/mass in a unit time in a particular direction is called velocity."
- In another way velocity can also be defined as The rate of change of displacement is called speed.
Velocity is always displacement/time. Its unit is m/s.
Example: Suppose you're traveling on your bicycle the rate at which the bicycle is moving is know as its speed. Velocity is then displacement (change of position) over time (speed+ direction)0Modal content

Velocity:
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 its speed and direction of motion (e.g.60 km/h to the north).
Velocity is a distance per unit time.
Velocity = Displacement / Time.
Its unit m/s0Modal content

Velocity is defined as the rate of change of displacement with time.
So the formula will be velocity = displacement / time.0Modal content
