because of the upthrust in water it weighs less and floats. An object in water will recieve an upthrust equal to the weight of water it displaces . submarines when neutrally ballasted could hang by the periscope that is just under the water raise periscope sub sinks down as water covers periscope starts to rise again,
Any floating object displaces its own weight of fluid.
What else can I help you with?
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.
Why does the weight of an object change in water?
because water weighs more than air, and there for, the weight difference between the water + object is less, making it seem as if the object has a smaller mass. Eg. Air = 0 (because we cant weigh it, so we set it as neutral) Water = 25 Object = 100 Object out of water = 100 Object in water = 75. Making it seem lighter
When an object is in water is it heavier or lighter?
When an object is in water, it may appear lighter because of the buoyant force acting on it. The buoyant force counteracts the weight of the object, making it feel lighter in water compared to in air.
Why an object underwater feels lighter than it is in air?
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.
Why does a heavy object feel lighter when under water?
A heavy object feels lighter in water because the upward buoyant force exerted by the water opposes the force of gravity acting on the object. This buoyant force counteracts the weight of the object, making it feel lighter.
Why does an object seem lighter in the water than in air?
Water constantly pushes upwards against an object making it seem lighter.

A heavy object feels lighter in water because the upward buoyant force exerted by the water opposes the force of gravity acting on the object. This buoyant force counteracts the weight of the object, making it feel lighter.
Is there any material that becomes heavier when submerged in water and lighter when it is taken out?
A porous object absorb water and is heavier. In air the water is evaporated and the object become lighter.
Why do the object become lighter in water?
Due to bouyency of water!
Why does an object feel lighter underwater than when its in the air?
An object feels lighter underwater because of the buoyant force exerted on it by the water. This force counteracts the gravitational force acting on the object, making it feel lighter.
Why do objects seem to be lighter in water than in air?
Objects are more buoyant in water than in air.
Why an object underwater feels lighter than when it is in air?
An object underwater feels lighter because of the buoyant force exerted by the water. This force counteracts the object's weight, making it feel less heavy. In contrast, in air, there is no buoyant force to offset the object's weight, so it feels heavier.
Why is there an upward force on objects water?
The upward force on objects in water is due to buoyancy. When an object is submerged in water, the water exerts an upward force on the object that is equal to the weight of the water displaced by the object. This helps support the object's weight, making it feel lighter in water.
