Objects are more buoyant in water than in air.
They are not really lighter, they only seem lighter. Objects weigh the same in water as in air, but in the water, there is an additional force, of the water pushing the object up.
Water constantly pushes upwards against an object making it seem lighter.
The ones that seem lighter most likely have smaller mass than the heavier ones. Either that, or else they're painted with a higher-gloss finish.
Only if you/people/animals/objects are lighter than water.
Yes, less dense objects float in water because they are lighter than the water they displace.
Objects that are less dense than water will float on the surface. This can include materials like wood, plastic, and certain types of metals. In general, objects with a density less than 1 g/cm3 will float.
There is a force called upthrust coming from the water. this pushes objects upwards, making the resultant force lower, which means they seem to weigh less.
Yes, mangoes are lighter than water. The density of mangoes is lower than the density of water, which means they will float in water.
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.
Refraction tends to make objects submerged in water appear shallower than they really are. This is because light rays bend as they pass from water to air, causing objects to appear higher than their actual position.
You can lift heavy objects more easily in water than in air because water provides more buoyant force than air due to its higher density. This buoyant force counteracts the weight of the object, making it feel lighter in water.
Saturn is much lighter than water. It is a gas giant made primarily of hydrogen and helium, with a density lower than that of water.
