Question
A heavy object seems lighter in water. Which force is responsible for this?
✓

Answer

When objects are placed in water, their mass does not change. They seem to feel lighter, though because of buoyancy. Archemedes's principle states that the force pushing on an object under water is equal to the mass of the water it has pushed out of the way.
