Homework Statement
If I have a solid sphere (I = (2/5)MR^2) and it rotates around a point on an axis that is 5m away (it has radius 0.1m) - is the moment of inertia then: I = (2/5)MR^2 + M*(4.9m)^2?
My question is - does the parallel-axis only work when we are moving the axis of rotation around "inside" the body or also outside it?
