## Initial Velocity Formula

The following equation is used to calculate the initial velocity of an object.

V1 = V2-t*a

- Where V1 is the initial velocity
- V2 is the final velocity
- t is the time
- a is the acceleration

## Initial Velocity Definition

An initial velocity is defined as the measure of the initial speed of an accelerating object.

## Initial Velocity Example

The following example review how to used the above equation to determine initial velocity.

- First, measure the final velocity of the object.
- Next, determine the total time that has passed.
- Next, determine the acceleration acting on the object during that time period.
- Finally, plug those three values into the formula above to get initial velocity.

For example, given V2=5, a = 2, t =2, solving: V1 = 5-2*2 = 5-1 = 1.

## FAQ

**What is initial velocity?**

Initial velocity is a movement an object has at the start of an observance period in which an acceleration starts to act on the object.
