What is the difference between matter and weight?

Answer 1

Matter has weight; weight is associated with matter. Matter can be visible; weight is a concept. Matter can change forms (water to ice to steam); weight has no transformation of such kind. A rock is a matter; the weight of a rock changes with altitude on earth and is lighter on Mars or the moon, while the mass of the rock does not change.

Answer 2

Matter refers to anything that has mass and occupies space, while weight is a measure of the force of gravity acting on an object's mass. In other words, matter is what makes up objects, while weight is the effect of gravity on that matter.

Answer 3

I think you might mean "Mass" and "Weight" - and the difference is the effect gravity has on things, and to a certain extent, the density of the item. For example, a pound of feathers and a pound of lead both WEIGH exactly the same (er...one pound, right?) but they have very different MASS. Also a hot-air balloon is rather massive, but does not have a lot of weight, relative to it's size.
