When an object is in water is it heavier or lighter?
lighter
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.
What is an object that floats in water?
something lighter than water
What is the true about an object that floats in water?
It is lighter than water
Why is a bucket of water lighter under water?
It actually isn't lighter, the mass of the bucket itself remains the same. However the buoyancy of the object, and the friction of water being higher than air, all work together counteract gravity. This makes the bucket appear to be lighter.

lighter

Why does an object seem lighter in the water than in air?
Water constantly pushes upwards against an object making it seem 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!

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 can't we measure the volume of an object if it floats on water?
Simply because the volume of water displaced is not equal to the actual volume of the object. If an object is lighter than water, you have to find another method of determining its volume. ------------------------------------ alternatively you could use a very thin pin to push the object under the water. However, the volume of the submerged portion of the pin would need to be suvtracted from the volume of the object measured.
What role does friction play when moving a heavy object?
It can make moving heavy objects easier for example sliding friction you can slide it or rolling friction you can roll the object across some kind of round cylinders or even fluid friction with water running under the object can make it easier.
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.
