It's a trick question, but with a not-so-trick answer:
The expected "correct" answer, is that since both "weigh" 1kg, they both have the same weight, and so neither one is heavier.
The CORRECT answer actually depends on a few more details, which will be explained in steps as follows:
1) The kg is a unit of mass, whilst weight, in the correct meaning of the word, is a measurement of forcemeasured in Newtons.
2) Force = mass x acceleration
-> Weight = mass x acceleration-due-to-gravity (g = 9.81 m/s2)
So up until now, we could argue that the stones and the feathers each have a weight of approx. 9.81 Newtons. However, so far we've only calculated the downward force on the two objects due to gravity.
Assuming that we're measuring the weight of these two objects somewhere on Earth, we must also consider the effects of the Earth's atmosphere, specifically the upward force this causes. Since air is a fluid, we must consider the effects of upthrust on these two objects:
3) Upthrust = weight-of-displaced-fluid
Now this is where things start to get interesting! Since we can safely assume that stone is more dense than feathers, then for the two objects to have the same mass of 1kg, the volume of the feathers must be greater than the volume the stone. Therefore, they will displace more of the fluid (air):
4) Stone-upthrust < Feathers-upthrust
So, getting back to weight:
5) Weight = downforce-due-to-gravity - upthrust-from-fluid
So, since the downforce due to gravity is equal in both instances, BUT the feathers produce more upthrust, the weight of the stone is, in fact, greater than the weight of the feathers.
Therefore, if they are both measured at the same location on Earth, 1kg of stone will be heavier than 1kg of feathers.
(Just don't tell your school Physics teacher this, unless you want him to think you're a smart-ass :-)
1kg=2.2lb 300g=10.6oz answer 1kg
1.000000001 kg is heavier
They both weigh the same, 1 kg
Neither! They both have the same mass of 1 Kilogram.
Oh, dude, 1 kg is definitely heavier than 100 g. I mean, like, 1 kg is like 1000 g, so it's like way more weight. It's like asking if a feather is heavier than a brick, you know what I mean?
Since they both have a weight of 1kg one cannot be heavier than the other.
Yes, 1kg of feathers is equal in weight to 1kg of stones. However, since feathers are less dense than stones, the volume of 1kg of feathers will be much larger than the volume of 1kg of stones.
1kg = 1000g
1kg is heavier because 1kg is equivalent to 1000g 700g is equal to .7kg
Since they both have a weight of 1kg one cannot be heavier than the other.
1kg=2.2lb 300g=10.6oz answer 1kg
1.000000001 kg is heavier
Both 1kg of sand and 1kg of cement have the same weight as they are both 1kg. The weight remains the same regardless of the material.
Cotton is a very lightweight plant, and fabric. Metal is much heavier than cotton.
1kg = 1000g7.75kg = 7750gSo, 7936g is heavier
Nooo, 1kg gold is heavier 1kg cotton, because the last one has much more volume than the first, so Archimedes force reduces weight of a cotton more!
Oh, what a lovely question! Both 1kg of feathers and 1kg of stones weigh the same because they both weigh 1 kilogram. Isn't that just delightful? It's all about the weight, no matter what the items are made of. Just remember, every little question is a happy little accident waiting to be understood.
