How To Use angular momentum In A Sentence
 The classical gyromagnetic ratio of an orbiting or a rotating electron is defined as the ratio of the magnetic moment to the angular momentum.
 The direction for torque and therefore angular momentum is given by the righthandrule.
 Up to this stage quantum theory was set up in Euclidean space and used Cartesian tensors of linear and angular momentum.
 Due to the total angular momentum conservation to the system centre of mass, the freedrifting spacecraft system becomes a nonholonomic one without considering the external forces moment acting on it.
 How did the planets pick up the necessary angular momentum, and why do the planets have different chemical compositions?
 The rate of change in the direction of the rotational axis is the ratio of torque to angular momentum and so gives a value for the precessional constant.
 Angular momentum is also important for scientists trying to understand subatomic physics.
 So there could be active periods where the gas cloud has oppositely directed angular momentum and power jets are established. Supermassive Black Holes Spinning Backwards Create Death Ray Jets?  Universe Today
 In section 6.5.1 the principle of conservation of angular momentum was outlined.
 The resulting system could have a huge angular momentum with a very welldefined direction.
