Acceleration Calculator is a free online tool that calculates the acceleration of an object effortlessly and quickly by taking the initial velocity, final velocity and time. Just you need to enter initial velocity (v), final velocity (u), and time (t) in the specified input sections of the calculator and press on the calculate button to find the acceleration in the blink of an eye.
Ex: 10, 167, 48, 34.5 or 90
Below mentioned are the simple steps to find the acceleration. Follow these guiding principles and get the result for your numbers in a less amount of time. Steps are along the lines.
Acceleration is the rate of change of an object speed. Its an vector quantity and has magnitude and direction. The acceleration formula is given as
Acceleration = Change in velocity / Time taken = (v - u) / t.
Average Acceleration = ∆v / ∆t =( vf - vi) / (tf - ti)
Question: A plane has a take off speed of 300 km/h. What is the acceleration in m/s2 of the plane if the plane started from rest and took 45 seconds to take off?
Final velocity (v) = 300 km/h
Time taken (t) = 45 seconds
As plane started from rest, initial velocity u = 0
Acceleration = (v - u) / t
We have to convert 300 km/h to m/s as time is in seconds.
300 km/h = 300 * 1000 m / 3600 sec = 83.3 m/ sec
By substituting these values in the acceleration formula, we get
Acceleration = (83.3 - 0) / 45 = 83.3 / 45
= 1.85 m/ sec2
Acceleration of the plane = 1.85 m/ sec2

1. What is meant by Acceleration?
Acceleration is defined as the rate at which object changes its speed or velocity. In simple terms, object is accelerating means its velocity is changing. As per the newton's second law, the acceleration is directly proportional to the force acting on a body and inversely proportional to the mass.
2. What is initial and final velocity?
Initial velocity means the velocity of an object before it has the effect of acceleration. After accelerating the object for some amount of time, the velocity will be the final velocity.
3. What is the difference between acceleration and average acceleration?
Acceleration of an object is change in object velocity over an increment of time. This can change when there a change in object speed or direction. Average acceleration is the change of velocity over a period of time.
4. Is zero acceleration constant acceleration?
Zero acceleration means there is no change in velocity i.e body is moving with same velocity. while constant acceleration means the velocity of an object increases or decreases with sane amount in same time. Therefore, both zero acceleration and constant acceleration are not same.
5. What acceleration is needed to accelerate a car from 36 km/h to 72 km/h in 25 seconds?
Initial velocity = 36 km/h = 36 * 1000 m / 3600 s = 10 m/s
Final velocity = 72 km/h = 72 * 1000 m / 3600 s = 20 m/s
time = 25 seconds
Acceleration = (20 - 10) / 25
= 10 / 25 = 0.4 m/s2
