Oh you so sitting on a ladder and one shot people from an distance doesnt count ?
Also i didnt knew glaive had more mass in steel then an axe. Thought more mass more impact but im prob wrong what i read about physics
You will get more momentum with an heavier object but if it's a perfectly balanced the difference wont be huge (of course an all steel stick will hurt more than a wooden stick but there's a reason why it's not really a valid war weapon).
Maces, Axes, and a number of polearm use an imbalanced design on purpose. By having all the weight concentrated on top of a lighter shaft, you increase the momentum exponentially from the added weight, hence increase the force of impact much more drastically than with a balanced weapon. The force will also increase to the length of the stick, giving the heavy mass more time to travel and pick up speed.
Something to do with centrifugal forces probably (but that's where my high school physics knowledge ends)
Anyway what matters more is not so much the total mass of a weapon, but also where is the center of its mass. A glaive or spear with a long blade will have a lower center of mass because of the blade shape (long) and the fact the weight is more evenly distributed along the length of the weapon. A hammer or an axe will have all the weight concentrated to the top which will bring its center of mass to the top (or very close). High center of mass means more momentum when swung around, at the expense of handling (you will need as much more strength to lift the mass up again)
For a sword the center of mass will be closer to the hand or further up the blade depending if you want to thrust with it or slash with it (that's why the design of the pummel and guard matters, as they serve as counterweights to the blade, typically a gladius made for chopping half-naked celts will have a higher center of weight than the medieval broadsword made for thrusting into chainmail)
