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)
Since speed or velocity = distance/time ,its dimensional formula =L/T = [MoLT-1]
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
The formula for calculating the maximum speed of an object is: max speed distance / time.
Velocity= Distance/ Time Unit= m/s
The formula for calculating velocity in a pipe is velocity flow rate / cross-sectional area.
The formula for calculating speed on an incline is V = √(2gh + u^2), where V is the final velocity, g is the acceleration due to gravity, h is the height of the incline, and u is the initial velocity. This formula takes into account the gravitational potential energy and the kinetic energy of the object.
The formula for calculating acceleration is: acceleration (final velocity - initial velocity) / time elapsed.
The formula for calculating acceleration is: acceleration change in velocity / time.
The change in time formula for calculating the velocity of an object is: velocity (final position - initial position) / (final time - initial time).
The formula for calculating fluid velocity in a pipe is V Q/A, where V is the velocity, Q is the flow rate, and A is the cross-sectional area of the pipe.
The formula for calculating the velocity of longitudinal waves is v (E/), where v is the velocity of the wave, E is the elastic modulus of the material, and is the density of the material.
