## Acceleration Formula

The following formula is used to calculate the acceleration of an object.

Acceleration = (Final Velocity – Initial Velocity) / Time

In Si units, acceleration is displayed as meters per second square (m/s^2), velocity is measure in meters per second (m/s), and time is measured in seconds (s).

The calculator above is unitless. This allows you to choose the units as it’s needed or displayed in your problem. Just be careful that the final units you write as your answer match those of your input. For example, if you input meters per second for velocity and s for time, the units should be m/s^2.

## How to Calculate Acceleration

We will now take a look at how to calculate the acceleration of an object. Let’s assume we are given an initial velocity, initial position, final position, and time. First, we need to layout our plan of attack for solving this problem. To calculate acceleration, we need both the initial velocity and final velocity.

To do this, we will calculate the average velocity through the change in position. Then, once we have the average velocity, we will use that and the initial velocity to calculate the final velocity.

Afterward, we have all the information we need and we can calculate the acceleration from the velocities and change in time.

## What is an acceleration?

Acceleration is also known as the rate of change of velocity, or in other words, the derivative of velocity with respect to time.
