How Do Boats Float?

January 14, 2020

So how do boats stay afloat? Luckily for you,
ScienceNation is here with an explanation! George let’s go! How can it be that this boat,
with all my weight on it, can stay afloat? Yet this small stone cannot? As an object enters the water, it displaces the liquid around it. The object will continue to sink until the weight of the displaced fluid matches the weight of the object. This is known as the Archimedes’ principle. Often heavier vessels, like cargo ships, will be much wider. This will increase the volume of air inside them and decrease their overall density. Even though the stone weigh less than the boat, it is smaller and so more dense than the water. Therefore it sinks.

    The stone is not less dense than water.. Otherwise it would float.
