physical phenomenon - a natural phenomenon involving the physical properties of matter and energynatural phenomenon - all phenomena that are not artificialacoustic phenomenon - a physical phenomenon associated with the production or transmission of soundatmospheric phenomenon - a physical phenomenon associated with the atmosphereboundary layer - the layer of slower flow of a fluid past a surfacechaos - the formless and disordered state of matter before the creation of the cosmoscloud - any collection of particles (e.g., smoke or dust) or gases that is visibledecalescence - phenomenon that occurs when a metal is being heated and there is a sudden slowing in the rate of temperature increase; slowing is caused by a change in the internal crystal structure of the metalelectrical phenomenon - a physical phenomenon involving electricityelectricity - a physical phenomenon associated with stationary or moving electrons and protonsenergy - any source of usable power; "the DOE is responsible for maintaining the energy policy"energy, free energy - (physics) a thermodynamic quantity equivalent to the capacity of a physical system to do work; the units of energy are joules or ergs; "energy can take a wide variety of forms"power - (physics) the rate of doing work; measured in watts (= joules/second)event - a phenomenon located at a single point in space-time; the fundamental observational entity in relativity theoryfield of force, force field, field - the space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with itforce - (physics) the influence that produces a change in a physical quantity; "force equals mass times acceleration"hysteresis - the lagging of an effect behind its cause; especially the phenomenon in which the magnetic induction of a ferromagnetic material lags behind the changing magnetic fieldresonance - an excited state of a stable particle causing a sharp maximum in the probability of absorption of electromagnetic radiationmechanical phenomenon - a physical phenomenon associated with the equilibrium or motion of objectsopacity - the phenomenon of not permitting the passage of electromagnetic radiationoptical phenomenon - a physical phenomenon related to or involving lightforce per unit area, pressure, pressure level - the force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit); "the compressed gas exerts an increased pressure"reflexion, reflection - the phenomenon of a propagating wave (light or sound) being thrown back from a surfacerefraction - the change in direction of a propagating wave (light or sound) when passing from one medium to anotherresolving power, resolution - the ability of a microscope or telescope to measure the angular separation of images that are close togetherresolution - (computer science) the number of pixels per square inch on a computer-generated display; the greater the resolution, the better the pictureconduction, conductivity - the transmission of heat or electricity or soundpropagation - the movement of a wave through a mediumfundamental interaction, interaction - (physics) the transfer of energy between elementary particles or between an elementary particle and a field or between fields; mediated by gauge bosonssurface tension - a phenomenon at the surface of a liquid caused by intermolecular forcessyzygy - the straight line configuration of 3 celestial bodies (as the sun and earth and moon) in a gravitational systemtransparence, transparency - permitting the free passage of electromagnetic radiationturbulence, turbulency - unstable flow of a liquid or gaschop - the irregular motion of waves (usually caused by wind blowing in a direction opposite to the tide); "the boat headed into the chop"floatation, flotation - the phenomenon of floating (remaining on the surface of a liquid without sinking)
