Accleration 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

Step by Step Process to Evaluate Accleration

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.

  • Let us take the initial velocity, final velocity, and time.
  • Evaluate the difference between final velocity and initial velocity.
  • Divide the obtained difference number by given time to get the acceleration value.

Accleration Formula

Accleration 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 = Γêåv / Γêåt =( 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?


Given that

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

Frequently Asked Questions on Accleration Calculator

1. What is meant by Accleration?

Accleration 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 accleration?

Accleration 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 accleration?

Zero accleration 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 accleration 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

Accleration = (20 - 10) / 25

= 10 / 25 = 0.4 m/s2
