Someone has suggested that these formulas amount to stating that the CoM is the mass-weighted average position of the collection of particles. Comment briefly on the validity/universality of this statement. (13 Yes; 9 No; 6 didn’t understand or gave confusing answers; 15 no answer) I don't think it's valid, because formula doesn't exactly give us the mass-weighted average position. You know, unless I'm understanding the question incorrectly. It is worded somewhat strangely. If by that statement the person means the relative mass weights the position, I would consider that valid universal as it basically just restates the formula. The word
