Fluids and Buoyancy

pushes an ice cube to the top of a glass of water

• buoyant force
• density
• a sinking object
• compressed air

explains why the the buoyant force on a rock that displaces 5 N of water is 5 N

• Bernouilli's principle
• MAK principal
• Archimedes. principle
• Harry Potter's law

has a weight of 10 N and a buoyant force of 10 N

• density
• a sinking object
• a floating object
• a buoyed-up object

has a weight of 15 N and a buoyant force of 18 N

• sinking object
• floating object
• buoyed up object
• my grandmother

can be decreased by making the shape hollow

• mass
• density
• volume
• weight

has a density of 2.5 g/cm³ in water

• floating object
• sinking object
• ice
• buoyed up object

is pumped into a submarine’s ballast tank to decrease density

• oil
