Navy Aviation Machinist Mate A School Week 1 Quiz 2023 with complete solution. 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.
