Definitions
Matter
Anything that has mass and takes up space.
Buoyancy
The upward force applied on an object when submerged in a fluid.
What is the first part of the particle theory?
Matter is made of tiny particles
what is an example of Pneumatic system?
Air breaks, pipe organs, dental drills, air nail gun, rock drills, spray gun
Which of the following is very compressible
Gas
Mass
Measurable amount of matter contained in a particle or object.
Pressure
The force exerted on the surface area per unit area.
What is the second part of the particle theory?
Particles are always moving or vibrating
What is an example of a hydraulic system
Gas pumps, construction equipment, car jacks, airplanes, elevators
Pneumatic systems use what medium to move mechanisms
Air
Density
Measurement of the ratio between mass and volume.
Viscosity
The measure of a fluid's flow caused by internal friction.
What is the third part of the particle theory?
There are spaces between particles
How can compressibility be explained by particle theory?
Particles are very close together in solids and liquids, they cannot compress further. Gas molecules are spread much farther apart.
Hydraulic systems most commonly use what state of matter to move mechanisms.
Fluids
Volume
The measurement of the amount of space an object occupies
Compressibility
Measure of volume change in a solid, liquid, or gas in response to a change in pressure.
What is the first Forth of the particle theory?
Particles are attracted to each other
Force
The push or pull of an object
Fluid
Substance that does not have a fixed shape and yields to external pressure.
