is the answer false because that is mass

false

Mass is the amount of matter present in object. Weight is the force exerted on that object due to gravitational pull.

You had me at mass, and lost me at weight. All I could think about was a box of feathers would be a lot lighter than the same size box of rocks!

In a gravitational field this is true, but in zero gravity they would weigh the same (0N), but the rocks would still have more mass.

Mass is the amount of stuff, weight is the amount of force needed to lift it, and is dependant on the gravitational field.

Don't confuse density (mass/volume) with weight or mass. The old kids' question, "which weighs more, a ton of feathers or a ton of lead?" comes to mind.

As started above, mass is a property of the material. If you were in zero gravity, any mass would have zero weight. On the moon where gravity is less, you would weigh less than you do on earth -- but you'd have the same mass.

We normally use weight to determine mass -- at least here on earth. However, in very accurate experiments, we have to correct for small changes in the force of gravity (gravity is less at higher altitudes, for example) and for the buoyancy of the material in air. The buoyancy requires a knowledge of the volume of the object.

Are y'all trying to teach me???

Capuchin

That's pretty much why we hang aroun dhere ;D

mum45

mmmhmmm. bouyancy of material in the air? ohboy, y'all ARE gonna teach me. see i just was all thinking "oh, yeah, rocks are really light in the water, I get it", then you start talking about bouyancy of material in the AIR!!!
Gets out the FAFSA..Going back to school in the fall. Dern it all.

LOL mum45... if ya come here, especially in the science threads, you sure will see yourself in school!
