TermDefinition
Archimedes's principle The priniciple 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.
Bernoulli's principle The principle that states that the fluid pressure of a flowing fluid decreases as its speed increases.
Boyle's law A gas law stating that the pressure and volume of a sample of gas at a constant temperature are inversely proportional.
buoyant force The upward force caused by the displacement of a fluid.
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.
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.
fluid Any substance that can flow.
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.
hydraulics The branch of physics concerned with the forces within and work done by liquids.
pascal The derived SI unit of pressure; 1 PA = 1 N/m2 = 1 kg/ms2
Pascal's principle The principle that states that pressure applied to a fluid is transmitted throughout the fluid.
pressure (P) A measurement of the amount of force acting upon a unit area.
viscosity A measure of a fluid's resistance to flowing.

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.
