If light objects only floats in water ,how will a ship float in water
The simplest boats, such as rafts, float because the material they are made of is less dense (lighter) than water. Heavy ships can float, because the water they are floating in pushes upward against them. This pushing force is called upthrust. The first experiment shows that an object will float if the upthrust of the water is great enough to overcome the downward push of the object’s weight. The size of the upthrust depends on how much water the object pushes out of the way. When you put an object in water and let it go, it settles into the water, pushing liquid out of the way. The further it goes in, the more water it pushes away and the more upthrust acts on it. When the upthrust becomes the same as the object’s weight, the object floats
