Do you know how to center the object?

How does the center of gravity affect the angular momentum of a rigid object?

• ok so when calculating the angular momentum of a rigid object i know that center of gravity affects how much momentum the object has. but when im calculating how do i put that into the formula. i've googled my mind away trying to figure this out. i have suspicions that it affects the radius when calculating but im not quite sure. please help an equation with a little explanation would do just fine also. thanks. if you need clarifications please say so.

• Answer:

  Angular momentum does not exist in mass unless the mass is rotating relative to another mass.the center of mass is the fulcrum where the rotational energies balance on both sides of the pivot point. Hence for angular momentum to takes place, at least 2 mass structures must rotate relative to Each other.Their angular speed ,and their period must match. Angular momentum can be defined as the product of the rotating energy and the period of time of the rotation. Thus if the rotational energy is calculated as well as the period of oscillation and their product is taken the result is called angular momentum. The equation of angular momentum is only valid for a rotating mass following the locus of a circle. Thus angular momentum of a mass is the spin of the mass. No spin no angular momentum exists. No mass no angular momentum. Theoretically a mass at rest has no Spin energy and no angular momentum. Therefore all rotations are relative to the presence of a mass nucleus.
