This is the section of Landau (about particles and potential energy assuming U is a homogeneous function)

I’m not very good with english, it isn’t my native language..., but I’m going to explain my question... I’m reading the first book of Landau's series ,it’s about clasical mechanics. In the second chapter you can find a problem about the conservation's theorem Homework Statement the problem...

Sorry for the bad english! M is constant when the movement is parallel to the axis of simetry of the field ie: a) if the field is a plane xy--->symmetry z axis--->M_z=doesnt change P is constant when the movement is in the "same field", in a) if the particle moves in any direction of x or y P...
