- | The angular momentum principle describes how the angular momentum of a system will change as a result of external torques. It is a vector principle as it describes how a system will rotate or translate in 3 dimensions. | + | **The angular momentum principle describes how the angular momentum of a system will change as a result of external torques.** It is a vector principle as it describes how a system will rotate or translate in 3 dimensions. |
