6.3.A—Describe the angular momentum of an object or rigid system

Describe the angular momentum of an object or rigid system.

• The magnitude of the angular momentum of a rigid system about a specific axis can be described with the equation
• The angular momentum of an object about a given point is Lr p =×    .
  • i. The selection of the axis about which an object is considered to rotate influences the determination of the angular momentum of that object.
  • ii. The measured angular momentum of an object traveling in a straight line depends on the distance between the reference point and the object, the mass of the object, the speed of the object, and the angle between the radial distance and the velocity of the object.
