General Knowledge Review


Capacitor - device used for storing energy, blocks direct current while allowing alternating current to pass, essential in tuned circuits
Current Formula (Ohms law) - V=IR where V=voltage, I=current, R=resistance in ohms
Impedance - total opposition to current flow
Resistor - device used in a circuit to provide resistance to current (converts electrical energy into heat energy)
Transistors -
Vacuum Tubes - give a lot of output for small amount of input
Voltmeter - has a large resistance and is used in parallel to measure voltage ( potential) in a circuit.
P = I2 x R where P=watts, I=amperes, R=ohms
Sample - an electrical loop has an output of 60 watts and a current of four amps.
What is the resistance. Answer -3.75 ohms
Volts = Amps x ohms
Volts x Amps = Watts (DC circuit)
Volts x Amps = Volt-Amps (AC circuit)
One Horsepower = 1000 watts
Why Tubes vs Resistors - greater output power, requires less voltage, amplifier

Acceleration = 9.8 meters/second2 or 32 feet/second2
Amplitude - the amount of work that a wave can do in displacing the molecules of the medium through which it travels
Boyles Law - if temperature is constant, the volume of a dry gas will vary inversely with the pressure exerted on it. PV = C where P = absolute pressure, V= volume, C = constant
Cooling- types of cooling - ambient adiabatic
Doppler effect - the change in pitch produced by the relative motion of the source and the observer. An object moving toward you has a higher frequency than one moving away.
Fission - the splitting of the nucleus of an atom into the nuclei of lighter atoms
Fusion - nuclei of light atoms join to form nuclei of heavier atoms
Joule - measurement of work in metric - a force of one newton acting through a distance of one meter
Newton's first law - an object at rest tends to stay at rest until acted upon by some external force
Newton's second law - the acceleration of an object acted upon by a constant force is directly proportional to the force and inversely proportional to the objects mass. In addition the acceleration occurs in the same direction as the applied force
Newton's third law - for every action there is an equal and opposite reaction
Pendulum - is an example of the conservation of total energy
Potential energy - stored energy
Kinetic energy - moving object
Scalar quantity - having magnitude (amount) not direction
Vector quantity - magnitude and direction
Vfinal = (Initial Velocity + Acceleration) x Time
(Vfinal)2 = (Initial Velocity)2 + 2A(Distance)
Four stroke engine - suck, squeeze, bang, blow
In comparison to a straight wing of the same area, a swept wing has the advantage of a higher critical mach number
A ball is thrown up 80 feet - how high up is it after .5 seconds? V=AT
Drop a ball - 5 seconds later what is the distance dropped? V=AT, D=1/2 a t2

Acids - sour taste, turns blue litmus paper to red, hydrogen is common to all acids. Ph less than 7. Produce hydrogen gas when interacting with metal
Bases - bitter taste, turns red litmus paper blue. Have a slippery feel (soap, sodium hydroxide, ammonia) Ph more than 7
Adiabatic - without gain or loss of heat
Adiabatic cooling - the cooling of air as it rises due to a decrease in pressure
Anode - the positive electrode of an electrolytic cell
Atomic number - number of protons in the nucleus
Atomic weight - average weight (mass of the protons plus neutrons) of the various isotopes of an element compared to the weight of a carbon-12 atom
Amplitude of a wave is the maximum value of the displacement of a wave from the mean
Amorphous solid - indeterminate, non-crystalline, ie glass
Atom - smallest particle which an element can be divided and still retain it's properties
Bound electrons - electrons in orbit in an atom
Cathode - the negative electrode of an electrolytic cell
Chlorophyl is used by plants to make glucose through photosysnthesis
Compass needles tend to line up parallel with the lines of force of a magnetic field
Concave Lens - thinner at the center than at the edges - focus light
Convex Lens - thinner at the edges than in the center - diffuse light - magnifying glass
Convection - tranfer of heat energy by the movement of heated matter An example of Convection is mixing two fluids of different temperatures together
Cybernetics - the study of communication and control both in machines and living organisms
Electron - the very small negatively charged particles which are almost weightless and circle the nucleus in orbits
Free electrons - electrons that have left their orbit in an atom and are wondering freely through a material; Electric current is movement of free electrons
Heat Transfer - in meteorology the two most important types are radiation and convection
Radiation - transfer of heat through space or the atmosphere with the speed of light
Conduction - transfer of heat energy through a substance be molecular contact
Ion common to all acids - (h+) hydrogen
Ion common to all bases - (OH-) hydroxide
Positive Ion - cation - it has less electrons than protons
Negative Ion - anion - it has more electrons than protons
Isotopes - are atoms that have the same atomic number but have a different number of neutrons
Latent heat - heat either absorbed or radiated during a change from liquid to vapor, solid to liquid, solid to vapor, and vice versa at a constant temperature and pressure
Mass Number - total number of nuetrons plus protons
Molecule - smallest unit which a substance such as water can be divided
Neutron - heavy neutral particles in the nucleus that behave like a combination of a proton and an electron
Nucleus - heavily positively charged central part of the atom
Photoelectric effect - electrons flow due to sunlight on metal
Proton - heavy positively charged particles in the nucleus
Positive charge - a deficiency of electrons
Negative charge - a surplus of electrons
Pascal's Law - pressure applied to a confined fluid at any point is transmitted equally in all directions and at right angle to the confining vessel
Refraction - bending of light rays, heat ray, or sound wave away from original direction when passing from medium of one density into that of another. No refraction occurs if the ray enters the surface at right angles
Mirage - deceptive appearance of distant objects caused by bending of light rays in layers of air of varying densities (refraction)
Transmutation - changing of one atom into another. Like trying to make gold from lead
Water exists in three forms - steam, liquid, and ice
Heat Speeds up chemical reactions - cold slows them down
Solids - have definite shape and volume usually described as crystalline or amorphous
Crystalline - solids with regular arrangement of particles (metals and other minerals)
Amorphous - have random particle arrangement, expands when heated, contracts when cooled (glass, plastics)
Pressure P=F/A where ….
The primary difference between a solid and a fluid is the degree of movement of the atomic or molecular particles
The measurement of temperature change is actually the measurement of changes in average kinetic energy

Now that's funny!!!
