they don't
Objects weigh less in water than in the air because water exerts an upward buoyant force on the object, partially offsetting its weight. This is known as buoyancy, which makes objects feel lighter in water than in air.
you would weigh 200 lbs. in water as you would on land. Your body just moved the water out of the way, which explains displacement. Buoyancy is what makes you seem lighter though. Because you weigh more than the water that you displaced and because the the water that you moved has a weight too, your body would be forced up after moving the water out of the way. So it's not that you weigh less in the water if someone picks you up, they just have more help when lifting you.
Objects that weigh less exert less downward force due to gravity compared to objects that weigh more. Gravity acts on all objects equally, causing them to fall at the same rate regardless of weight. However, weight is a measure of the force of gravity acting on an object's mass, so objects with more mass will have a greater weight and exert a greater force on a surface when supported.
Objects with more mass weigh more because weight is directly proportional to mass. The gravitational force acting on an object is stronger when the object has more mass, resulting in a greater weight measurement.
An aluminum cube would weigh less in water than in air. This is because water exerts an upward buoyant force on objects submerged in it, which partially offsets the downward force of gravity acting on the cube.
no. water put on water makes more water. its the same as land on land. put land on land, makes more land not dyer land.
ask einstein
There is more water on earth than land.
it has more water than land because earth is made of water
Yes, there is more water than land.
An object floats on water when the buoyant force acting on the object is greater than the weight of the object. This buoyant force is exerted by the water displaced by the object, pushing it upwards. Objects that displace more water than they weigh will float, while objects that displace less water will sink.
One million is a number, and as such, it is a concept rather than a physical object, and has no weight. You could weigh a million objects but you would have to say which objects they are; a million elephants weigh more than a million apples.
