Enter the final and average acceleration into the calculator to determine the Initial Acceleration. 

Initial Acceleration Formula

The following equation is used to calculate the Initial Acceleration.

Ai = 2*AA – Af

  • Where Ai is the Initial Acceleration (m/s^2)
  • Af is the final acceleration (m/s^2)
  • AA is the average acceleration (m/s^2)

What are the units for Initial Acceleration?

In the International System of Units, also known as SI units, the units for Initial Acceleration are m/s^2.

How to Calculate Initial Acceleration?

Example Problem:

The following example problem outlines the steps and information needed to calculate the Initial Acceleration.

First, determine the final acceleration. In this example, the final acceleration is calculated or measured to be 40 (m/s^2).

Next, determine the average acceleration. For this problem, the average acceleration is determined to be 30 (m/s^2).

Finally, calculate the Initial Acceleration using the formula above: 

Ai = 2*AA – Af

Inserting the values from above and solving the equation with the imputed values gives: 

Ai = 2*30 – 40 = 20 (m/s^2)
