Why do objects feel lighter in water than in air?

Answer 1

Because water has a higher density than air so ther is more bouyant force countering gravity. Gravity pulls things down. Bouyancy pushes things upward. The more bouyancy an object has, the less it will appear to weigh. Remember, if something is floating on the srface of water, it will weigh nothing because if you put a scale under it, it won't even touch the scale.

Answer 2

buoyancy, density, and Archimedes principle.......hope that helped!

This scientific riddle first observed and solved by Archimedes.

When a body is immersed in water, then water, equal to the volume of the body, is displaced. The simple reason is that the space, required by the body to occupy, must be provided.

This displaced water makes the level in the container to get raised by a smaller amount. If the container is large, then we cannot even sense this rise. Any way, there is a rise. The displaced volume of the liquid, thus placed above the initial surface of the liquid would exert a thrust, which will be equal to the weight of the displaced liquid. This action, downward, would bring a reaction as per Newton's third law and that reaction appears to act on the immersed body in the upward direction and hence it is named as buoyant force. This upward force would reduce the weight of the body which is acting downward.

Hence the immersed body appears to lose weight. This excellent experience made Archimedes to come out with a shout "Eureka, Eureka" -means found out , found out.
Because the water produces an upthrust on the body, equal to the weight of the water displaced. Interestingly the water also causes an upthrust on each 'bit' of water. If this was not the case the 'bits' of water would also fall to the bottom.
Because water is denser than air so some of the weight is supported by the water, the more saline the water the less the object will weigh or at least seem to be lighter. That is why people can float in the dead sea with out even trying.

Answer 3

because there is no gravity in water to weigh the object down

Answer 4

Because of the effect known as buoyancy: the apparent weight of the object is reduced by the weight of the displaced water (which is about 1 kg/1000 cm3 or 62.4 lb/ft3).

Answer 5

no no
