Forces in Fluids

QuestionAnswer
fluid any material that can flow and that takes the shape of its container
pressure the amount of force exerted on a given area, expresses in pascals
pascal the SI unit of pressure, equal to the force of 1 N exerted over an area of 1 square meter
atmospheric pressure the pressure coaused by the weight of the atmosphere
density the amount of matter in a given space, mass per unit volume
Pascal's principle principle that states that a change in pressure at any point in an enclosed fluid is transmitted equally to all parts of that fluid
buoyant force the upward force that fluids exert on all matter, opposes gravitational force
Archimedes' princple principle that states that the buoyant force on an object in a fluid is an uopward force equal to the weight of the volume of fluid that the object displaces
Bernoulli's principle states that as the speed of a moving fluid increases, the pressure will decrease
lift an upward force on an object tha opposes the downward pull of gravity, pressure above and below the object contributes
thrust the forward force produced by an airplane's engines, opposes drag
drag force that opposes or restricts motion in a fluid, opposes thrust
atmosphere the layer of nitrogen, oxygen and other gases that surrounds the Earth
displace to take the place of
buoyed up pushed up
swim bladder organ in fish that filles with gas produced in the blood to make a fish less dense
turbulence an irregular or unpredictable flow of fluids that can cause drag, lift is reduced by this
hydraulic a device that uses liquids to transmit pressure from one point to another

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
