Cartesian+Diver+Submarine

__ How Submarines Work __ : An upside-down test tube will be used to model a submarine. Submarines pump water in and out to change their density to sink and float using Archimedes' Principle. Use Pascal’s Principle to put pressure on the air inside the test tube to allow more water in. Watch the application of Archimedes' Principle as the test tube floats and sinks. than water it will float.

The volume of displaced water is greater. Density = mass/volume

When more water is displaced there is more buoyant force.

Buoyant force is equal to the mass of the water displaced. (Archimedes’ Principle)

Floating occurs when the weight of the water displaced is equal to or greater than the mass of the vessel. || || When the object is more dense than water it will sink.

The volume of displaced water is less. Density = mass/volume

When less water is displaced there is less buoyant force.

Buoyant force is equal to the mass of the water displaced. (Archimedes’ Principle)

Sinking occurs when the weight  of the water displaced is less than  the mass of the vessel. || __Archimedes Principle and Pascal's Principle__ a) The buoyant force acting on a submerged object is equal to the weight of the volume of the water displaced by the object. b) Copy the diagram on how a submarine works (and relate it to density and Archimedes’ principle).

c) Write down Pascal’s Principle and comp the fluid pressure figure on p. 433. Answer the question.
