Is angular momentum equal to Inertia times Omega and why?
1 Answer
see below
Explanation:
Angular momentum is also known as the moment of momentum
consider a rigid body rotating about a fixed axis with angular velocity of
the definition of
ie
consider the rigid body is made up from particles each of mass
then the moment of momentum ( call it
where
but for angular motion
so
For the total angular momentum we have to sum up all the particles
so angular momentum is moment of inertia
in vectors the formula is
