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 iron 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 iron 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 iron. Therefore, they will displace more of the fluid (air):
4) Iron-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 iron is, in fact, greater than the weight of the feathers.
Therefore, if they are both measured at the same location on Earth, 1kg of iron 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 :-)
Both are equally easy to lift since they both weigh 1 kilogram. The difference lies in the volume and density of the objects. The steel would be denser and therefore smaller in volume compared to the feathers.
No, both 1kg of lead and 1kg of feather would weigh the same in a vacuum because weight depends on mass, and both objects have a mass of 1kg. Gravity affects weight, but in a vacuum, there is no air to provide resistance, so both objects would fall at the same rate.
Both of them are just the same. A kilogram is the same as akilogram
Half of 1kg is 500g.
0.5kg is half of 1kg.

They both weigh the same = 1KgThe answer is there in your question

Neither! They both have the same mass of 1 Kilogram.

Because it would be a lot smaller.and also feathers weigh les so that would be more feathers you would have to carry.; )
I believe it is approximately 1.13 cubic meters (1.13 litres will lift 1 gram; do the math.
The 1kg magnet will exert a greater force on the 0.5kg piece of steel, causing them to move towards each other. The 0.5kg steel piece will accelerate faster towards the magnet due to the greater force acting on it by the magnet.
As long as they're both on the same planet, every kilogram weighs the same. Put 1 kg of stones and 1 kg of feathers (or 1 kg of smoke or 1 kg of water or 1kg of dust) on opposite ends of a see-saw, and they balance.
Since kilograms are the unit we use to measure mass, the answer is no: both have 1kg. of mass. :D
1kg = 1000g
1kg=2.2lb 300g=10.6oz answer 1kg
