Computing[ edit ] The slash, sometimes distinguished as " forward slash ", is used in computing in a number of ways, primarily as a separator among levels in a given hierarchy, for example in the path of a filesystem. File paths[ edit ] The slash is used as the path component separator in many computer operating systems e. In Unix and Unix-like systems, such as macOS and Linuxthe slash is also used for the volume root directory e. The slash in an IP address e.
So the unit of power is the watt not Wattabbreviated W; the unit of energy is the joule not Jouleabbreviated J; and so on.
It can be focused to affect a much tighter or larger effect zone, but there will be some spreading at the target, even if it's only very slight.
It can travel through a vacuum.
A wave is a force effect that has to travel through a medium. Sound is a wave, because it's vibrations force in a substance like air or water. A wave can be pointed in a specific direction, but tends to spread out much more than a ray.
It cannot travel without something to travel in. Light is a special case, in that it acts both like a particle and like a wave. It can be confusing, so try to read up on what effect you're intending of it before saying one way or the other.
Quantum Physics The study of physics at the atomic and subatomic scale, where particles react in ways that seem to make very little sense. Example of high voltagevery low current circuit is the shock you get from static electricity when you walk around on dry carpeting. Its water analogy is pressure.
An example of large current, low voltage flow would be the current through the tip of a soldering gun. Its water analogy is volumetric flow rate. In the case of electric circuit, it is the dot product of voltage and current.
Its water analogy is still power - this concept exists across all physics. A natural example of dielectric breakdown of air is lightning. Its water analogy would be the pressure sustained by a thickness of barrier before it breaks - think of a bit of balloon skin tied over the end of a water faucet.
Energy Energy can be defined as "the ability a physical system has to do work on other physical systems" Wikipedia. It can appear in several forms, such as kinetic movement energy, electromagnetic radiation, and potential energy.
Energy cannot be destroyed or created, but only changed into other forms of energy or matter. There is no such thing as 'pure energy', as energy cannot be impure, though it is sometimes used in reference to the energy of mass, which is released as high-energy photons and low-mass particles such as pions.
Also note that 'energy beings' of science fiction are often formed from plasma, which possesses energy but is still a phase of matter. The mass of an object, measured in kilograms or pounds lbm measures the amount of matter there's in an object.
A direct measurement of this would follow from measuring the inertia of the object, then working out the radius of gyration for its geometry, and using the equation. The weight of an object, measured in Newtons, pound-force lbf or kilogram-force, is a measurement of the force by which an object is pulled by gravity.
A good example of measuring weight would be a spring balance. Due to the units' definition, most non-scientists don't distinguish between them, and it is fine as long as you are on Earth, or since we're at the Foundation nowhere near a gravity-altering anomaly.
Once g changes, the usage of especially kilograms can get confusing since eg. In short, when using kg or pounds, specify whether you are referring to mass or weight.Welcome to the United States Air Force subreddit. Feel free to discuss anything about the Air Force or military in general.
List of approved abbreviated/shortened words for EPRs/Awards (timberdesignmag.comce) submitted 1 year ago by cnstarz. Or hell they are using it as an EPR/OPR bullet or whatever civilians use for evaluations. permalink. Air Force Core Values. Integrity First, Service Before Self, and Excellence in All We Do.
Acknowledgement. The Tongue and Quill has been a valued Air Force resource for decades and many Airmen from our Total Force of uniformed and civilian members have contributed their talents to various.
Bullet Statement Format Watch that Format. Anyone who's been through Airman Leadership School knows that bullet statement format is the format required for entries in the AF Form How to Write an EPR.
Writing an EPR is one of the supervisor's most important responsibilities because the EPR is the only official record of an individual’s performance during his or her Air Force career.
EPRs must accurately and clearly capture what the ratee has accomplished during the reporting period.

For the construction of the pyramids, the ancient Egyptians had to transport heavy blocks of stone and large statues across the desert.
The Egyptians therefore placed the heavy objects on a sledge.
