3 True or False Science Questions?

Question

1. Weight and mass are the same?
2. Weight varies according to location on the earth?
3. You would weigh more on Mount Mitchell than at Wrightsvill Beach?

True or False

Answer 1

1.FALSE. weight is measured in grams. mass, in volume
2. TRUE. things weigh less when close to the north and south poles
3. FALSE. mount mitchell is at a higher elevation. that means less gravitational pull which means you would weigh less on the mountain than on the beach

Answer 2

Out of the 19 replies here, 12 posted "False True False". All 19 posted "False" for 1), only 2 posted "False" for 2), and 5 posted "True" for 3). It shows that, once again, aggregrate intelligence in a population is frequently much higher than average and I would recommend that you go with "False True False".

1) "Weight" actually has the physical dimensions of Force, not mass. Force = mg, where m is mass, and g gravitational acceleration. Kudos, everyone.
2) If you weigh yourself using a scale on the ground at different locations on Earth, you won't get the exact same readings everywhere, because of a number of factors, including a) Earth is not really perfectly round 2) Earth spins, and 3) Earth's crust varies in thickness and density, but less than average upper mantle density.
3) There's several reasons why one would weigh less on Mount Mitchell, including the following: a) further away from center of Earth (horizon of land mass slightly below level) b) centrifugal force from Earth's rotation slightly higher, and c) being on a mountain, the lithosphere is thicker, which is less dense than upper mantle. Wrightsvill Beach is assumed to be roughly at the same latitude as Mount Mitchell.

Answer 3

1 False. Every thing that has a mass has a pulling force. As the mass increases, this pulling force increase. Since Earth is so big, it has a big pulling force which is called the Gravity. The force by which something is being pulled is its weight. So, weight may change when you are on moon or another planet. Weight is measured in Newtons. On the other hand, mass can be said to be the amount of matter in something which will be the same in any place under any condition. Mass is fixed and measured in grams.
2 True. Since Earth is not circular, it has some places that are farther from the core than other places.In the places which is farther from the core, you can imagine that there is more matter beneath you pulling you which gives you more weight.
3 I don't know, but i think true for the same reason in the second question

Answer 4

1. Weight and mass are not the same - False
2. Weight varies due to different gravity pull ann can be affected by tide. - True
3. Test to prove that tou weigh more on mount mitchell than at wrightsvill beach.

Answer 5

False, mass is how much of you there is, weight is the force in which gravity pulls that mass.
True, very small difference though, not even a scale could measure it.
False, The farther away you are from the surface of the earth the less you weigh.

Answer 6

1 False, weight is dependant on gravity, mass is not.

2 True, the further from earths center of gravity the less you weigh.

3 False, you'd weigh more on the beach.

Answer 7

1. False. Something could be great in mass but small in weight. Like if you had 2 sacks of feathers and one sack of oranges. Even though you had two sacks of feathers, they'd still way less.
2. True. The lower you are in the atmosphere the less you way.
3. True. Same as # 2. The air is thicker the higher the elevation.

Answer 8

False - weight is a force, mass is the amount of matter in an object.
True
False - The farther away from Earth one is, the lighter (because gravitational attraction decreases over distance). So you would weight more on the beach (assuming it's by an ocean).

Answer 9

FALSE - weight and mass are similar, but not exactly the same
TRUE OR FALSE - depending on what you mean by "location". If location refers to longitude and latitude, then it's false. If it refers to altitude, then it's true.
FALSE - you'd weigh less on top of the mountain because you'd be farther from the earth. (assuming, of course, that the mountain is higher than the beach)

Answer 10

1. False
2. True
3. False
