Acceleration Formula. Which is the change in velocity of object with the passage of time. If the velocity of an object changes from an initial value u to the final value v in time t, the acceleration a is given by, a=(v-u)/t and this kind of motion is called accelerated motion.
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. For instance, imagine you’re a drag racer. Your acceleration is 26.6 meters per second2, and your final speed is 146.3 meters per second. Now find the total distance traveled. Got you, huh? “Not at all,” you say, supremely confident. “Just let me get my calculator.”
You know the acceleration and the final speed, and you want to know the total distance required to get to that speed. This problem looks like a puzzler, but if you need the time, you can always solve for it. You know the final speed, vf,and the initial speed, vi (which is zero), and you know the acceleration, a. Because vf – vi = at, you know that
Now you have the time. You still need the distance, and you can get it this way:
The second term drops out because vi = 0, so all you have to do is plug in the numbers:
In other words, the total distance traveled is 402 meters, or a quarter mile. Must be a quarter-mile racetrack.

Acceleration
There are a few. The most famous is a = F/m, whereF is the net force applied to a mass, m.
Acceleration is also the change in velocity, (Delta-V), dividedby the change in time, (Delta-t). So, a =Δv/Δt.
For example, if an object's velocity changes from 10 meters persecond to 20 meters per second in five seconds, its acceleration is(20-10)/5 = 2 meters per second per second, or 2 meters per secondsquared (m/s2).
For circular motion, centripetal acceleration is v2/r, wherev is the linear velocity of the rotating object andr is the radius of its circular path.
Acceleration is the second derivative of position with respectto time: d2x / dt2, which makes it the firstderivative of velocity: dv / dt. Therefore, theacceleration is the slope of the curve on the velocity-versus-timegraph.
Thus:
a = dv / dt = d2x / dt2
Acceleration is a quaternion with real and vector parts:
cv/Rcos(v) is the Centrifugal Acceleration a part of thereal accelerations in the first parenthesis. The second parenthesiscontains the vector accelerations.
Acceleration = F/m, where F is the netforce applied to a mass, m.
a=f/m,
acceleration in terms of velocity.
a = v - u/t Delta Velocity divided by Time.
A = ΔV ÷ T Acceleration is worked out by (final speed - initialspeed)/ time taken for change in speed a = v2-v1/ t2-t1 Strictlyyou should say velocity ie the speed in a certain direction.Youalso have the formula f=ma which tells you that the force neededto get something moving will be the mass of the object multipliedby the accelertion you want to achieve; so from this formula if youknow force and mass you can work out acceleration. The formula foracceleration is: Vf-(Vi)/t ie. change in velocity per unit time.Instantaneous acceleration in its differential form is d2x/dt2where x is a function of time t.
Acceleration is the time rate of change of velocity.
That is, acceleration =dv/dt (v - velocity ; t -time)
