Measurements
mL or cm cubed
What is the measurement for volume?
This occurs when the buoyant force is greater than the gravitational force.
What is floating?
True or False. Objects that displace a greater volume of fluid are more buoyant than those that displace less fluid.
What is true?
g or kg
What is the measurement for mass?
The density of saltwater was greater than the boat.
Why does the boat float?
The buoyant force acting on an object equals the weight of the fluid displaced.
What is Archimedes' Principle?
1.0 g/mL
What is the density of (distilled) water?
A controllable, balloon-like chamber that allows fish to alter their buoyancy.
What is a swim bladder?
g/mL or g/cm3
What are the units for Density?
Length x Width x Height
How will you calculate volume of rectangle or square?
This tool floats at different levels in different liquids because the liquids push it upward with different forces.
What is a hydrometer?
The density will decrease, molecules spread out and take up more volume. The mass stays the same.
What happens to the density of a substance that is heated?
Specialized chambers that can be filled with air or water to control the depth of the submarine.
What are ballast tanks?
Newtons
What is the measurement used for buoyant force?
By submerging the object in the water and measuring how much the volume of the water increases. The amount of displaced water represents the volume of the submerged object.
How will you find the volume of an irregular object?
The upward force exerted on an object submerged in the fluids.
What is buoyant force?
These markings show at what level a ship will float in different types of water.
What are plimsoll or load lines?
This occurs when the submarine or fish remains in one place, neither rising nor sinking.
What is neutral buoyancy?
