Enter the final velocity, the initial velocity, and the change in time, into the calculator to determine the Rate of Acceleration. 

Rate of Acceleration Formula

The following equation is used to calculate the Rate of Acceleration.

A = (A2-A1) / dT
  • Where A is the Rate of Acceleration (m/s^2)
  • A2 is the final velocity (m/s)
  • A1 is the initial velocity (m/s)
  • dT is the change in time (s)

To calculate the rate of acceleration, subtract the initial velocity from the final velocity, then divide by the time.

What are the units for Rate of Acceleration?

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

How to Calculate Rate of Acceleration?

Example Problem:

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

First, determine the final velocity. In this example, the final velocity is calculated or measured to be 50 (m/s).

Next, determine the initial velocity. For this problem, the initial velocity is determined to be 20 (m/s).

Next, determine the change in time. In this case, the change in time is found to be 2 (s).

Finally, calculate the Rate of Acceleration using the formula above: 

A = (A2-A1) / dT

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

A = (50-20) / 2 = 15 (m/s^2)
