AND SOLUTIONS RATED A+
✔✔ 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
