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.
Well, darling, a kilogram is definitely heavier than an ounce. An ounce is like a feather compared to a kilogram, which is more like a brick. So, if you're looking to lift some serious weight, go for the kilogram and leave the ounce for measuring your precious gemstones.
One kg
Because it's five times heavier of course !
If it were, it would be rather difficult to lift, and probably too big to fit a pencil through. A pencil sharpener is more likely to weigh 50 grams, if it is one of a mechanical variety.
A seesaw acts as a force multiplier because it uses the principle of leverage, allowing a smaller force applied at a greater distance from the fulcrum to lift a heavier load positioned closer to the fulcrum. This mechanical advantage is achieved through the seesaw's pivot point, which amplifies the input force based on the ratio of the distances from the fulcrum to the points where the forces are applied. As a result, it enables one person to lift another who may be significantly heavier, demonstrating how the arrangement of forces and distances can enhance lifting capability.

She struggled to lift the heavier suitcase onto the overhead bin.
It is easier to lift a load with a lever. You exert a large force over a small distance on the load end by exerting only a small force over a greater distance at the effort end. The following equation, and example, may help you visualize it.load arm X load force = effort arm X effort forceNow imagine that you have a one kilogram rock, and a one gram feather. If you place the the rock 1 cm to the left of the fulcrum, and the feather 1 meter to the right of the fulcrum, the two will be balanced. This is because the feather is 1000 times farther from the fulcrum than the rock. So, even though the rock is 1000 times heavier than the feather, the feather has a mechanical advantage, which balances it out on the fulcrum.
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.
Heavier than What?
no
One kg
The weight of the box felt heavier than expected as I tried to lift it.
Yes, a Chinook could lift an Apache. -I've seen them lift guns heavier than an Apache.
The large one on a birds wings; they produce lift.
The answer is two fold: Real and Psychological. The Real part is explained by the relationship between mass and force. When you lift anything up what you feel is the force it exerts on your system (your hand for example) and not the weight. 1kg or iron exerts more unit force on your hand because its mass is concentrated in smaller area. On the other hand, 1kg of feather has its mass distributed over a wider area and therefore exerts a smaller unit force. It therefore genuinely feels lighter. The psychological bit is that we automatically expect something big to weigh more than and item far smaller than it. Of course it won't be if they are the same weight. Your perception therefore is that if "feels" lighter.
The amount that a healthy person can lift depends on their height and weight.
