Unit 6 – Gravity, Mass, Density & Weight, Buoyancy, Bernoull’s Principle, Scalling

Buoyancy Playground

This site has a simulation that allows you to float certain things into an oil base or water base and calculate what happens when you place an object in it. There are scales at the bottom to record how much force or (N) is being displaced. The interactive model really allows the player to simulate what is happening when buoyancy occurs.

Bernoulli’s Principle – Physics Experiment

Bernoulli’s principle states the following,

Bernoulli’s principle: Within a horizontal flow of fluid, points of higher fluid speed will have less pressure than points of slower fluid speed.

This means that as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. … Since the speed is greater in the narrower pipe, the kinetic energy of that volume is greater.

What’s below the Tip of the iceberg? – Camille Seaman

It’s a well-known fact that the majority of an iceberg lies below the surface — but just as stealthily hidden are their fascinating qualities. Traveling the seas, teeming with life, and sometimes even making a noise called “bergie seltzer,” there’s so much more than meets the eye. She lists the ranges in size normally like small, medium. large, and very large. Then she compares to a car, a house, and even a 27 story building.

How Does a Steel Ship Float Using Archimedes’ Principle?

Archimedes’ buoyancy principle states that buoyant force — what keeps the ship afloat — is equal to the weight of water that is displaced when the ship enters the ocean. If the weight of displaced water is at least equal to the weight of the ship, the ship will float. The displaced water around a coin weighs less than the coin, so the coin will sink.
