physical phenomenon

Noun
  1. A natural phenomenon involving the physical properties of matter and energy (synset 111439518)
    is a type of: natural phenomenon - all phenomena that are not artificial
    subtypes:
    • acoustic phenomenon - a physical phenomenon associated with the production or transmission of sound
    • atmospheric phenomenon - a physical phenomenon associated with the atmosphere
    • boundary layer - the layer of slower flow of a fluid past a surface
    • chaos - the formless and disordered state of matter before the creation of the cosmos
    • cloud - any collection of particles (e.g., smoke or dust) or gases that is visible
    • decalescence - 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 metal
    • electrical phenomenon - a physical phenomenon involving electricity
    • electricity - a physical phenomenon associated with stationary or moving electrons and protons
    • energy - any source of usable power
    • 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
    • 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 theory
    • field, field of force, force field - the space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with it
    • force - (physics) the influence that produces a change in a physical quantity
    • 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 field
    • resonance - an excited state of a stable particle causing a sharp maximum in the probability of absorption of electromagnetic radiation
    • mechanical phenomenon - a physical phenomenon associated with the equilibrium or motion of objects
    • opacity - the phenomenon of not permitting the passage of electromagnetic radiation
    • optical phenomenon - a physical phenomenon related to or involving light
    • force 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)
    • reflection, reflexion - the phenomenon of a propagating wave (light or sound) being thrown back from a surface
    • refraction - the change in direction of a propagating wave (light or sound) when passing from one medium to another
    • resolution, resolving power - the ability of a microscope or telescope to measure the angular separation of images that are close together
    • resolution - (computer science) the number of pixels per square inch on a computer-generated display; the greater the resolution, the better the picture
    • conduction, conductivity - the transmission of heat or electricity or sound
    • propagation - the movement of a wave through a medium
    • fundamental interaction, interaction - (physics) the transfer of energy between elementary particles or between an elementary particle and a field or between fields; mediated by gauge bosons
    • surface tension - a phenomenon at the surface of a liquid caused by intermolecular forces
    • syzygy - the straight line configuration of 3 celestial bodies (as the sun and earth and moon) in a gravitational system
    • transparence, transparency - permitting the free passage of electromagnetic radiation
    • turbulence, turbulency - unstable flow of a liquid or gas
    • chop - the irregular motion of waves (usually caused by wind blowing in a direction opposite to the tide)
    • floatation, flotation - the phenomenon of floating (remaining on the surface of a liquid without sinking)
