Matter
Anything that takes up space. Can change from one state to another. Made up of
Elements or Compounds.
states of matter
solid, liquid, gas
Solid
state of matter with a definite shape and volume
liquid
A state of matter that has a definite volume but no definite shape.
Gas
A state of matter with no definite shape or volume
Volume
the amount of space an object occupies
Mass
the amount of matter in an object
Weight
A measure of the force of gravity acting on an object
Gravity
Force that attracts an object towards the center of the earth
Density
Amount or quantity of mass per unit volume
Force
The total pressure acting upon an object
Pressure
Force per unit area measured in PSI
Types of Pressure
Static Pressure
Impact Pressure
Relative Pressure
Absolute Pressure
Static Pressure
Pressure in a confined space or not causing motion
Impact Pressure
pressure caused by motion
Relative Pressure
One pressure in relation to another
Absolute Pressure
Sum of the Atmospheric Pressure and System pressure starting from a theoretical
vacuum
Pascal's Law
, Pressure applied to enclosed or confined fluid is transmitted equally in all directions
without loss, and acts with equal force on all surfaces.
Bernoulli's Principle
States whenever a stream of any fluid has it's velocity increase at a given point the
pressure of the stream at that given point is less than the rest of the stream.
Divergent Venturi tube
Decrease velocity and increase pressure
Convergent Venturi tube
increase velocity and decrease pressure
Boyle's Law
States the volume of a given mass of a gas varies inversely with pressure when
temperature is constant
Charles' Law
States if the volume of a confined gas is constant the pressure is directly proportional to
the absolute temperature or if the pressure is unchanged the volume is proportional to
the temperature
Newtons Laws of Motion
Law of interia
Law of Force and Acceleration
Law of Interaction
Law of Interia
Newtons first Law
States a mass at rest will stay at rest while a mass in motion will stay in motion until
acted upon by an outside force.
Law of force and acceleration
Newtons Second Law
When a body is acted upon by a constant force the acceleration is inversely proportional
to it's mass
F=ma
Law of Interaction
Newtons 3rd Law
For every action there is an equal and opposite reaction
Heat
Form of energy produced by motion of molecules known as kinetic energy
British thermal unit
Calorie
Methods of heat transfer
conduction, convection, radiation
Conduction
transfer of heat from molecule to molecule
Convection
transfer of heat by means of currents in a fluid caused by uneven heating (boiling water)
Radiation
Transfer of heat by means of high speed particles of energy
Temperature
Intensity of hotness/coldness of a mass measured in degrees.
