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.

Vf = Vi + a * t

• Where Vf is the final velocity
• Vi is the initial velocity
• a is the acceleration
• t is the time

Typical units for these values are m/s for velocity, m/s2 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?

1. First, determine the initial velocity.

Measure the initial velocity.

2. Next, determine the acceleration.

Calculate the total acceleration.

3. Next, determine the time.

Measure the total time.

4. Finally, calculate the final velocity.

Calculate the final velocity using the formula above.

## 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.

How is final velocity calculated?

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