Enter the height at which an object is being dropped from into the calculator to determine the impact velocity.

## Impact Velocity Formula

The following formula is used to calculate an impact velocity.

v = Sqrt ( 2 * g * h )

- Where v is the impact velocity (m/s)
- g is the acceleration due to gravity (9.8 m/s^2)
- h is the height of the object (m)

## Impact Velocity Definition

An impact velocity is the total speed of an object when it makes impact with the ground or another object after falling from a certain distance.

## Impact Velocity Example

How to calculate impact velocity.

**First, measure the height of the object.**Determine the total height the object is to be dropped from. For this example we will say the height is 10m.

**Calculate the impact velocity.**Using the formula, calculate the impact velocity. : sqrt ( 2*9.8*10) = 14 m/s.

## FAQ

**What is an impact velocity?**

An impact velocity is a measure of the speed of an object when it impacts another surface. It’s most often used when analyzing objects that are dropped from a certain height.
