Mass vs. Weight???Mass is the

measurement of the amount of matter in a given amount

of a substance.

Weight is the

measure of the pull of gravity on a given

mass.

BUT. . .

In other words. . .

The weight of an object on earth is greater than the weight of the same object on the moon, since the Earth

has more gravity than the moon.

The mass of the object (the amount of stuff) is the same on the earth as

it is on the moon.

Mass is the amount of stuff.

Weight is the affect of gravity

(measured by a scale) on a given

mass.

However . . .On Earth, the mass in grams

equals the weight in grams. So for values ON EARTH we often use

the terms weight and mass interchangeably. Just be careful, because where gravity values are different from on Earth (the moon, in space, another planet, etc.) the mass will be the same as on Earth but the weight will be different!

account gravityB: mass measures the amount of

stuff while weight measures gravity's affect on mass

grams
