Because an object immersed in water is buoyed upward by a force equal to
the weight of the displaced water, so the stone's net weight in water is less
than it is in air, by a difference of roughly 62 pounds for each cubic foot of
its volume.
because the amount of force in water is equal to the amount of force in water
If the question is asking "for what reason would a person lift a heavy stone immersed in water as opposed to air?" then the answer is buoyancy. When immersed in water there will be an upward force on the bottom of the stone due to the volume of water it has displaced. This upward force will make the stone seem lighter to the person lifting it by decreasing the amount of force they need to exert to lift it.

you can use a 300ml graduated cylinder water,3different objects
14lbs = 1 stone
due to higher intensityof heavy stone than a lighter stone
12.2 stone is 77.47kg
due to higher intensityof heavy stone than a lighter stone
inclined planes reduce the amount of work to do, its easier to push a heavy stone rock up a ramp then carrying it
6.5 stone = 41.4 kg
234 stone = 1,485.97 kg
11.5 stone is 73.03 kilos.
