How do Boats Float?


How can a boat, which is many times larger than yourself, float instead of sink on water? The answer is science, and I will share the specifics.

Buoyancy is the force that causes some objects to float on water. Density is the amount of matter in a given volume. Water has a density of 1, so anything with a density greater than 1 will sink, and anything less dense than water will float. This means that a boat has less density than water.

Also, there’s something called upthrust. Upthrust is a net force that supports the boat from underneath the water. The boat sinks, but is supported up by upthrust.

Here are some links for more information:

This relates to engineering because engineers would have to design a boat that will float on water. They will have to think of density and buoyancy, as well as what materials to use.
