types:
Energie,
Leistung
(physics) a thermodynamic quantity equivalent to the capacity of a physical system to do work; the units of energy are joules or ergs
Kraft
(physics) the influence that produces a change in a physical quantity
Druck
the force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit)
Reflexion
the phenomenon of a propagating wave (light or sound) being thrown back from a surface
Brechung
the change in direction of a propagating wave (light or sound) when passing from one medium to another
Wolke
a visible mass of water or ice particles suspended at a considerable altitude
Alternativenergie
energy derived from sources that do not use up natural resources or harm the environment
Blutdruck
the pressure of the circulating blood against the walls of the blood vessels; results from the systole of the left ventricle of the heart; sometimes measured for a quick evaluation of a person's health
Ladung
the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons
Strom
a flow of electricity through a conductor
Elektrizität
energy made available by the flow of electric charge through a conductor
Arbeit
(physics) a manifestation of energy; the transfer of energy from one physical system to another expressed as the product of a force and the distance through which it moves a body in the direction of that force
Wetterfront
(meteorology) the atmospheric phenomenon created at the boundary between two different air masses
Sturm
a violent weather condition with winds 64-72 knots (11 on the Beaufort scale) and precipitation and thunder and lightning
optische Illusion
an optical phenomenon that results in a false or deceptive visual impression
Polarisierung
the phenomenon in which waves of light or other radiation are restricted in direction of vibration
Spannung
the difference in electrical charge between two points in a circuit expressed in volts
Wasserdruck
the pressure at a given point in a liquid measured in terms of the vertical height of a column of the liquid needed to produce the same pressure
Öldruck
pressure that keeps oil on the moving parts of an internal-combustion engine
Gasdruck
(physical chemistry) the pressure exerted by a solution necessary to prevent osmosis into that solution when it is separated from the pure solvent by a semipermeable membrane
Schalldruck
the difference between the instantaneous pressure at a point in a sound field and the average pressure at that point
Strahlung
energy that is radiated or transmitted in the form of rays or waves or particles
Spannkraft
(physics) force that produces strain on a physical body
Sonnenaufgang
atmospheric phenomena accompanying the daily appearance of the sun
Dampfdruck
the pressure exerted by a vapor; often understood to mean saturated vapor pressure (the vapor pressure of a vapor in contact with its liquid form)
Klima,
Wetter,
Wetterlage
the atmospheric conditions that comprise the state of the atmosphere in terms of temperature and wind and clouds and precipitation
