What else can I help you with?
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.
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.
Does an object become heavier when placed in water?
No. It becomes lighter as the water exerts an upthrust on the object according to the archmides' principle. Thus the reaction force ( or the weight ) of an object becomes less.
Why does an object seem lighter in the water than in air?
Water constantly pushes upwards against an object making it seem lighter.
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.
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 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 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 an object seem lighter in water?
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.
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.
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
Explain why an object under water feels lighter when its in the air?
When an object is underwater, it displaces an amount of water equal to its weight. This buoyant force pushes the object upward, effectively reducing its weight. When the object is above the water, it is no longer displacing water, so the buoyant force is removed, making it feel heavier.
