How in the world do boats float?


Going to pearl harbor was a pretty fun experience, though it would have been more fun if it wasn't so hot and muggy. Anyways, the field trip was exciting because we got to ride on a boat and look inside submarines. While I was on the boat, I thought to myself, "Wow, there are a lot of people on this boat. How come this boat doesn't sink?" Then it hit me again. Buoyant force was the answer, something we recently reviewed in our packets. Buoyant force is the force that pushes up on a ship and is equal to the weight of the water displaced. Therefore, as long as the boat displaces enough water to counter the weight of the ship and its passengers, the boat will not sink. Once again, it is amazing how physics is hidden in almost every aspect of our lives, and how it makes our lives more convenient
