Enter the initial angular momentum (kg-m^2/s) and the change in angular momentum (kg-m^2/s) into the Calculator. The calculator will evaluate the Final Angular Momentum. 

Final Angular Momentum Formula

pf = pi + dp

Variables:

  • pf is the Final Angular Momentum (kg-m^2/s)
  • pf is the initial angular momentum (kg-m^2/s)
  • pi is the change in angular momentum (kg-m^2/s)

To calculate Final Angular Momentum, add the change in momentum to the initial momentum.

How to Calculate Final Angular Momentum?

The following steps outline how to calculate the Final Angular Momentum.

  1. First, determine the initial momentum (kg-m^2/s). 
  2. Next, determine the change in momentum (kg-m^2/s). 
  3. Next, gather the formula from above = pf = pi + dp.
  4. Finally, calculate the Final Angular Momentum.
  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.

initial momentum (kg*m/s) = 45

change in momentum (kg*m/s) = 70
