Enter the change in velocity expended (m/s) and the expected theoretical change in velocity (m/s) into the Calculator. The calculator will evaluate the Gravity Loss.

## Gravity Loss Formula

GL = dVe - dVt

Variables:

- GL is the Gravity Loss (m/s)
- dVe is the change in velocity expended (m/s)
- dVt is the expected theoretical change in velocity (m/s)

To calculate Gravity Loss, subtract the expected theoretical change in velocity from the actual change in velocity expended.

## How to Calculate Gravity Loss?

The following steps outline how to calculate the Gravity Loss.

- First, determine the change in velocity expended (m/s).
- Next, determine the expected theoretical change in velocity (m/s).
- Next, gather the formula from above = GL = dVe – dVt.
- Finally, calculate the Gravity Loss.
- 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.

change in velocity expended (m/s) = 4500

expected theoretical change in velocity (m/s) = 300
