PS Chapter 16:Fluids

PS Chapter 16: Fluid Mechanics Coach Leach

TermDefinition
fluid Any substance that can flow.
pressure A measurement of the amount of force acting upon a unit area.
pascal The derived SI unit of pressure.
Pascal's principle The principle that states that pressure applied to a fluid is transmitted throughout the fluid.
buoyant force The upward force caused by the displacement of a fluid.
Archimedes's principle The principle that states that an immersed object displaces an amount of fluid equal to its volume and that the weight of the displaced fluid is equal to the buoyant force acting on the object.
viscosity A measure of a fluid's resistance to flowing.
Boyle's law A gas law stating that the pressure and volume of a sample of gas at a constant temperature are inversely proportional.
Charles's law A gas law stating that the volume and absolute Kelvin temperature of a sample of gas at constant pressure are directly proportional.
Gay-Lussac's law A gas law stating that the pressure and absolute Kelvin temperature of a sample of gas at a constant volume are directly proportional.
combined gas law A gas law that states that the ratio of the product of a gas sample's pressure and volume to its absolute Kelvin temperature is a constant.
hydraulics The branch of physics concerned with the force within and work done by liquids.
Bernoulli's principle The principle that states that the fluid pressure of a flowing fluid decreases as its speed increases.

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.
