If you lift 1 kg iron and 1 kg cotton what is more heavier in lifting?

Answer 1

Hi Dhara,

1kg is a unit of measurement. Different amounts or quantities of objects and items can equal 1kg. Since both the feathers and the iron each weigh 1kg, there is no difference and each weighs the exact same. While it may take significantly more feathers than pieces of iron to get to 1kg, they will both be the same. I hope that helps!
