Initial Velocity Calculator

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

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

Example

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

  1. First, measure the final velocity of the object.
  2. Next, determine the total time that has passed.
  3. Next, determine the acceleration acting on the object during that time period.
  4. 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.
