buoyant force
The upward force on an object placed in a fluid is called the _________________________ .
Image: buoyant force
gravity
The downward force pushing on an object is called _________________ .
Image: gravity
fluid
It doesn't have a fixed shape. It consists of liquids and gases that can "flow".
Image: fluid
displaced fluid (water displacement)
Synonym for the amount of fluid pushed out of the way when an object is dropped into the fluid.

positive buoyancy
If the buoyant force acting on the object is stronger than the force of gravity, it is called ________________.
Image: positive buoyancy
negative buoyancy
If the force of gravity acting on the object is stronger than the buoyant force, it is called ____________ .
Image: negative buoyancy
Archimedes Principle
an object will sink until it floats. It will sink until enough water is displaced equal to the mass of the object.
increases
The pressure of the fluid on an object __________________ the further down the object goes in the fluid.
decreases
The pressure of the fluid on an object ____________ the closer the object is to the surface of the fluid.
