Enter the air density and the true airspeed into the Calculator. The calculator will evaluate the Lift Energy.

## Lift Energy Formula

LE = 1/2*p*V^2

Variables:

- LE is the Lift Energy (J)
- p is the air density
- V is the true airspeed

To calculate Lift Energy, multiply the air density by the true airspeed squared, then divide by 2.

## How to Calculate Lift Energy?

The following steps outline how to calculate the Lift Energy.

- First, determine the air density.
- Next, determine the true airspeed.
- Next, gather the formula from above = LE = 1/2*p*V^2.
- Finally, calculate the Lift Energy.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

air density = 4.5

true airspeed = 400
