3Weight is the measure of the pull of gravity on a given mass. Mass vs. Weight???BUT. . .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.
4In 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.
5Weight is the affect of gravity (measured by a scale) on a given mass. Mass is the amount of stuff.Weight is the affect of gravity (measured by a scale) on a given mass.
6However . . .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!
20Mass and weight are different because A: weight measures amount of stuff while mass takes into account gravityB: mass measures the amount of stuff while weight measures gravity's affect on massC: gravity has no affect on weight or massD: mass is measured in pounds while weight is measured in grams
21Mass is the measure of the amount of material. A: TrueB: False
22When gravity acts upon a particular mass it is measured as weight. A: TrueB: False
23A 10kg mass is weighed on Earth and on the moon A 10kg mass is weighed on Earth and on the moon. The moon has less gravity. Which of the following is true?A: The mass weighs more than 10kg on Earth and less than 10kg on the moon.B: The mass weighs 10 kg on Earth and more than 10 kg on the moon.C: The mass weighs 10 kg on Earth and on the moon.D: The mass weighs 10kgs on Earth and less than 10kgs on the moon.
24D: there is no way to tell Mars has less gravity than Earth. What will the mass of a 41g ball be on Mars?A: more than 41gB: less than 41gC: 41gD: there is no way to tell
