3 Weight 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.
4 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.
5 Weight 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.
6 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!
20 Mass 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
21 Mass is the measure of the amount of material. A: TrueB: False
22 When gravity acts upon a particular mass it is measured as weight. A: TrueB: False
23 A 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.
24 D: 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
25 Pedro uses a triple beam balance scale in science lab to measure the mass of an apple. He determines the apple to have a mass of 120 grams. What is the weight of the apple in SI units?A: 5.2 ouncesB: 60 gramsC: 120 gramsD: 0.2 pounds
26 A standard sized paperclip has a mass of approximately one gram A standard sized paperclip has a mass of approximately one gram. What would you estimate to be the mass of a golf ball?A: 45 gramsB: 1 kgC: .45 gramsD: 10 kg
27 Which of the following is NOT a SI unit? A: KelvinsB: kilometersC: degrees CelsiusD: degrees Fahrenheit

32 What is the length of the black line in millimeters? C: 5 and three quartersD: 570
33 It is good practice when using a meter stick to measure from the 1 cm mark instead of the end. What is the length of the black line in cm?A: 19.8B: 18.8C: 198D: 188
34 What is the temperature reading of the thermometer pictured? A: 28 degrees FahrenheitB: 28 KelvinC: 28 degrees CelsiusD: 20 degrees Celsius
