Fluids

3. the amount of force applied to a given area
4. the tendency of an object in a fluid to rise or sink due to density differences with its surroundings
7. a disk that moves inside a cylinder
9. a device that moves fluid through or into something
10. the push or pull of an object
12. System: a group of parts, including at least one fluid, that interacts with each other and function together as a whole
14. a fluid system that uses two pistons of different sizes to create pressure to lift a vehicle
15. Law: stated when a force is applied to an enclosed fluid, the increase in pressure is transmitted equally to all parts of the fluid
18. the measure of how much space a substance takes up
21. Line: shows how heavily a ship can be loaded safely in different water conditions
22. the measure of how much matter there is in a substance
23. a mixture of water and solids
24. anything that has mass or volume
25. Rate: a measurement of the speed at which a fluid flows from one point to another
26. any substance that flows
27. System: a system that uses a gas, usually air, under pressure to transmit a force

1. a device that controls the flow of the flui
2. The amount of mass contained in a given volume
5. a decrease in volume caused by a force
6. the resistance of a fluid to flow
8. Force: the upward force exerted by a fluid
11. Expansion: an increase in the volume of a substance in response to an increase in its temperature
13. to make a solution
16. memorize 5 main points to the particle theory of matter)
17. a force that works to slow down motion as a result of surfaces rubbing against each other
19. Theory of Matter: the theory that states that all matter is made up of particles; that all particles of one substance are identical, the particles of matter are in constant motion; that temperature affects the speed at which particles move; that particles have forces of attention between them; and that there is space between particles
20. System: systems that use liquid under pressure to transmit a force
