Actually, unlike common belief there is no exact formula. Scientists (that is the more advanced ones) estimate the speed and velocity of an object or person by looking at it and making a so called "Scientific Guess". It is pretty technical but i think you can understand this brief explanation.
If the velocity is constant, thenDisplacement = (initial velocity) multiplied by (time)
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
Net acceleration = (change in velocity) divided by (time for the change)
If you are travelling at an average velocity, it is simply the average velocity multiplies by the time travelled at that speed. Otherwise you can use the following formula: x = ut + 1/2at^2 where: x = displacement from origin u = initial velocity (m/s) t = time (seconds)62 a = acceleration (m/s^2
Since speed or velocity = distance/time ,its dimensional formula =L/T = [MoLT-1]
Velocity= Distance/ Time Unit= m/s
Veloicty is distance divided by time, for a object moving in a given direction. If direction is not given, then it is speed.
No. Velocity states both speed and direction.Time gets involved in calculating the speed.
There are different formulae for calculating these variables which depend on what information is available.
Divide distance by time.

Velocity = Distance/Time for most all movement problems While the above formula is true for most movement problems, air speed is not a velocity. Air speed is speed of an aircraft relative to the surrounding air. The air speed of a hot air balloon is always zero because it is not moving through the air.
Velocity (speed) = distance/time
Velocity = Speed / Time So, in the context of a triangle, speed would be at the top.
Distance = speed x time
Net acceleration = (change in velocity) divided by (time for the change)
