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
