Can someone please explain to me what moment of inertia means??
I googled it and I found that moment of inertia is an objects resistance to angular momentum? What does that mean exactly? Can someone please briefly explain to me (in English) what it means or give me an example? Because I really need to understand the concept in order to answer a question like this:
If global warming continues over the next one hundred years, it is likely that some polar ice will melt and the water will be distributed closer to the equator.
(a) How would that change the moment of inertia of the Earth?
increase
decrease
no change(b) Would the duration of the day (one revolution) increase or decrease?
increase
decrease
no change
