Flashcards in Chapter 3.1-3.3 Deck (11):
1

fluid

any material that can flow and takes the shape of it's container

2

pressure

the amount of force exerted per unit area of a surface

3

pascal

the SI init of pressure

4

atmospheric pressure

the pressure caused by the weight of the atmosphere

5

buoyant force

the upward force that fluids exert on all matter

6

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

7

Bernoulli's principle

states that the speed of a moving fluid increases, the fluid's pressure decreses

8

lift

an upward force on an object that moves in a fluid

9

thrust

the pushing or pulling force exerted by the engine of an aircraft or rocket

10

drag

the force that opposes or restricts motion in a fluid

11

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.
