Why Do Cruise Ships Float

Water displacement occurs when the boats force pushes the water out and away from it keeping it steady in the water and afloat.

Why do cruise ships float. It doesnt take much to appreciate the fascinating science that keeps these massive vessels afloat. There are three basic concepts that explain how and why a ship can float. Cooking oils are less dense than water which is why they sit on the top of pots of water.

A small solid object might not float however. A ring might be small but its more dense than the same sized space of water. The Science Behind How a Ship Floats.

The displaced water attempts to return to its original position now occupied by the ship which pushes the ship up. You must have known of the mysterious force called gravity that pulls everything down towards the earth Bottom surface. A cruise ship has a very large base giving the water it sits on ample space to push against.

Ships are often made of wood some kinds of which are less dense than water and some of which are more dense. Sprawling cruise ships some even containing parks and neighbourhoods roam the worlds oceans every day. This is that force that makes the ship to float but stone or needle to sink.

October 30 2016 Not everything thats heavy sinks right to the bottom of the ocean floor and theres no greater proof than Royal Caribbeans Harmony of the Seas which happens to be the biggest cruise ship on Earth. Ships float because they displace enough water for the buoyancy force to be greater than the force of gravity acting on the ship. It sinks down further displacing more water bigger shaded area.

This is a great resource for teaching children. There are hundreds of ships moving hundreds of thousands of guests and crew from port to port every single day. So if the force exerted downward on the object by gravity is less than the buoyant force the object will float.
