Velocity is a measure of how quickly an object moves. For instance imagine you re a drag racer.

The letter a is short for acceleration due to gravity.
Physics formula of velocity. Simplify the formula using short symbols as shown below. So the velocity is the change in the position of an object divided by the time. In a physics equation given a constant acceleration and the change in velocity of an object you can figure out both the time involved and the distance traveled.
Velocity definition physics the time rate of change of displacement of an object in a particular direction is called its velocity. The merton rule was first published in 1335 at merton college oxford by the english philosopher mathematician logician and calculator william heytesbury 1313 1372. Its dimensional formula is m lt 1.
To find the velocity use the equation. It is a vector quantity as it has both the magnitude and direction. A comprehensive list of all the physics formulas.
This article provides a comprehensive physics formulas list that will act as a ready reference when you are solving physics problems. Final velocity initial velocity acceleration due to gravity time. The unit for velocity is meters per second m s.
Velocity formula in physics velocity frac text displacement text time taken its si unit is m s. Average velocity is the total displacement by total time and is given by v x t where x is the total displacement of the body and t is the time. Vf v0 a t vf v0 and t stand for final velocity initial velocity and time.
Learning physics is all about applying concepts to solve problems. When the rate of change of a quantity is constant its average value is halfway between its final and initial values. Velocity will have the magnitude as well as a specific direction.
V v v0. The average velocity formula in case δx is the displacement vector and δt is the time interval of displacement is the following. Velocity has a magnitude a value and a direction.
In simple way it is v frac d t in other way the velocity formula physics is v frac change in position time. Now find the total distance traveled. Instantaneous velocity is the velocity of a body at any given time.
V velocity m s x f the final position m x i the initial position m t the time in which the change occurs s. Your acceleration is 26 6 meters per second 2 and your final speed is 146 3 meters per second. You can even use this list for a quick revision before an exam.
Velocity v displacement time δx δt thus velocity is the rate of change of displacement with time. The general way to calculate the constant velocity of some object moving in a straight line is to divide the distance by time taken.
