Enter the initial velocity, acceleration, and total time into the calculator to determine the final velocity of an object.

## Final Velocity Formula

The following formula is used to calculate the final velocity of a moving object.

V_{f} = V_{i} + a * t

- Where V
_{f}is the final velocity - V
_{i}is the initial velocity - a is the acceleration
- t is the time

Typical units for these values are m/s for velocity, m/s^{2} for acceleration, and seconds to for time. With that said, other values can be used as long as they match up. For example, m/s could be ft/s as long as acceleration is then ft/s^2.

## Final Velocity Definition

A final velocity is defined as the final speed of a moving object with an initial velocity and acceleration over some time.

## Final Velocity Example

How to calculate final velocity?

**First, determine the initial velocity.**Measure the initial velocity.

**Next, determine the acceleration.**Calculate the total acceleration.

**Next, determine the time.**Measure the total time.

**Finally, calculate the final velocity.**Calculate the final velocity using the formula above.

## FAQ

**What is a final velocity?**

A final velocity is the speed at which an object is moving after having gone through an acceleration over some time.

**How is final velocity calculated?**

Finally velocity is calculated by adding the acceleration times time to the initial velocity.
