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.

  1. First, determine the change in velocity expended (m/s). 
  2. Next, determine the expected theoretical change in velocity (m/s). 
  3. Next, gather the formula from above = GL = dVe – dVt.
  4. Finally, calculate the Gravity Loss.
  5. 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
