An object underwater feels lighter than it does in aor because of buoyancy.
Buoyant force acts in the opposite direction to the force of gravity so it makes the object feel lighter

Are objects lighter 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.
Explain why an object under water feels lighter when its in the air?
Objects underwater feel lighter than it is in the air because water density is greater then air density.
Why do air bubbles in water rise to the surface?
Air is lighter than water.
Why is there an upward force on objects water?
A floating object in water means its mass is smaller than water and therefore it floats. just like helium baloons float upward because it is lighter than air
Is moist air heavier or lighter than dry air?
Moist air is heavier than dry air, because of the water.
Why do objects seem to be lighter in water than in air?
Objects are more buoyant in water than in air.

Why does a helium balloon go up?
A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.
What is the direction of acceleration for an object in the air?
Heavier than air objects accelerate downwards. Lighter than air objects accelerate upwards until they are no lighter than the air around them.
Do plastic float on water?
depends if the plastic is heavier or lighter than water and if its hold air which is lighter than water
Why do air bubbles in water rise to the surface?
Air is lighter than water.
Why is there an upward force on objects water?
A floating object in water means its mass is smaller than water and therefore it floats. just like helium baloons float upward because it is lighter than air
What happens when heated air is lighter than the surrounding air?
Lighter air will rise; it is the same phenomenon as an air bubble rising in water.
Is moist air heavier or lighter than dry air?
Moist air is heavier than dry air, because of the water.
Why is water heavy yet the elements in it are either air or lighter than air?
Water isn't "heavy." Liquid water is more dense than air, yes, but water vapor is (significantly) lighter than air. Water is a liquid at temperatures far higher than what might be expected based on its molecular weight because of hydrogen bonding.
Why does an object seem lighter in the water than in air?
Water constantly pushes upwards against an object making it seem lighter.
