## 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 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. For this example, problem, the initial velocity is measured to be 50 m/s.

Next, determine the acceleration. During the duration of the movement, this object accelerates at a are of 5m/s^2.

Next, determine the total time of acceleration. The object in this example accelerated for a total time of 5 seconds.

Finally, calculate the final velocity using the formula above:

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

V_{f} = 50 + 5 * 5

V_{f} = 75 m/s.

## FAQ

**What is a final velocity?**

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