Here two derivations of Hamilton’s equations of motion are examined and found to depend crucially on both the system being conservative and the mass being constant. It is speculated that these derivations might be extended to the case where, as well as the system being conservative, the mass varies purely with time. However, at this stage, other generalisations seem unlikely and, if that is so, the usefulness of the Hamilton approach in mechanics would appear to be limited.
Comments: 4 Pages. Again it is hoped this short note will provoke more examination of this topic.
