# Acceleration Calculator

Use our acceleration calculator if you need to know **how to find acceleration** using different variables such as velocity, time, distance traveled, or mass and force. The tool consists of three formulae for **acceleration in physics**, which you can select in the first box of the calculator.

The following article presents concise information explaining, e.g., what acceleration is and how to calculate acceleration. Furthermore, we show **solutions to the below popular problems**:

- How to find acceleration with velocity and distance;
- How to find acceleration with velocity and time; and
- How to find time with acceleration and distance.

The acceleration equation is **strictly related to the velocity**. We have prepared a separate tool for the latter physical quantity. You can find it under this average velocity calculator link.

## Acceleration formula in physics

The acceleration measures **how velocity changes over time**. With this basic definition, you should be able to tell what the acceleration formula is:

where:

- $a$ - The acceleration;
- $\Delta v$ - The velocity change; and
- $\Delta t$ - The time change.

If the change in velocity is not constant, then you should use derivatives instead of finite change (but that's a completely different story). The above equation is a simple **average acceleration formula**.

The second option in the acceleration calculator helps you if you need to know how to find acceleration with velocity and distance $d$:

where, this time, $v_0$ is the initial velocity.

Finally, let's see what the equation for acceleration is from the perspective of Newton's second law:

where:

- $F$ - The net force acting on an object; and
- $m$ - The mass of the object.

From the practical point of view, acceleration plays a vital role in **fuel consumption**, which you can estimate with our fuel efficiency calculator.

## How to find time with acceleration and distance

This constant acceleration calculator can make calculations in any direction you want. For example:

- The initial speed is $10 \text{ m/s}$.
- The distance is $100 \text{ m}$.
- The acceleration is $1 \text{ m/s}^2$
- Input all the above values in the corresponding acceleration calculator field in the mode "Distance traveled", and you'll find that time equals $7.32 \text{ s}$.

What is the acceleration formula we used in that case? It arises from one of the **quadratic equation solutions** with respect to $t$ based on the acceleration formula with distance:

All the above considerations are about linear motion. The story is entirely different if you want to include the **rotational aspect**. You can, for example, calculate rotational kinetic energy of an object that is not moving at all, just rotating.
