## Theoretical Velocity Formula

The following equation is used to calculate the Theoretical Velocity.

TV = SQRT ( 2*g*H)

- Where TV is the theoretical velocity (m/s)
- g is the acceleration due to gravity (m/s^2)
- H is the height (m)

## What is a Theoretical Velocity?

Definition:

A theoretical velocity describes the maximum speed an object falling from a given height would reach if there was no air resistance.

## How to Calculate Theoretical Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Theoretical Velocity.

First, determine the acceleration due to gravity. This is equal to 9.81 m/s^2.

Next, determine the height. For this problem, the height is found to be 30m.

Finally, calculate the Theoretical Velocity using the formula above:

TV = SQRT ( 2*g*H)

TV = SQRT ( 2*9.81*30)

TV = 24.26 m/s
