Chapter 3.1-3.3 Flashcards
fluid
any material that can flow and takes the shape of it’s container
pressure
the amount of force exerted per unit area of a surface
pascal
the SI init of pressure
atmospheric pressure
the pressure caused by the weight of the atmosphere
buoyant force
the upward force that fluids exert on all matter
Archimedes’ principle
states that the buoyant force on an object in a fluid is an upward force equal to the weight of the fluid that the object takes place of
Bernoulli’s principle
states that the speed of a moving fluid increases, the fluid’s pressure decreses
lift
an upward force on an object that moves in a fluid
thrust
the pushing or pulling force exerted by the engine of an aircraft or rocket
drag
the force that opposes or restricts motion in a fluid
Pascal’s principle
states that a change in pressure at any point in an enclosed fluid will be transmitted equally to all parts to that fluid.
