Question

How can a ship float on water as metal 's density is more than water?

Answer 1

even tho the density of the metal is more than that of water, however the density of the "ship" is less. the ship isn't exactly a metal ball, it's a structure.

Answer 2

Hey mate,

▪When an object is immersed in water there are different forces which act on the object namely gravitational force, buoyant force and frictional force.

▪Gravitational force is a downward acting force. Buoyant force is the upward force acting on an object when it is immersed in a medium which is equal in magnitude to the weight of the liquid it displaces. Frictional force resists downward movement and thus acts in the upward direction.

▪When,

Downward forces > Upward forces ---> Object sinks

▪When,

Downward forces < Upward forces---> Object floats

▪When,

Downward forces = Upward forces ---> Object remains suspended

▪The boat is designed or shaped in such a manner that the mass of water the boat displaces is less than the mass of the boat or alternatively the downwards forces < upward forces, hence the boat floats.

Hope it helps !!
