Understanding Angular Momentum: Inertia Increase

AI Thread Summary
An increase in angular momentum in an object is associated with an increase in its rotational inertia, which is distinct from mass. While mass remains constant, the moment of inertia, which quantifies an object's resistance to changes in its rotational motion, can increase with angular acceleration. This increase in inertia is specifically related to the distribution of mass around the axis of rotation, affecting how the object responds to applied torques. Understanding this distinction is crucial for grasping the dynamics of rotational motion. Further details can be explored through resources like HyperPhysics.

If an object undergoes an angular momentum increase, its inertia is increased. I am trying to understand what part of its intertia is increased. As I understand it inertia and mass are directly related, and I don't think that an object that undergoes angular acceleration has a mass increase. Is the increase in inertia soley rotational? If anyone could give me any insight on this it would be considered very helpful.

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
