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; "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 theory
field 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 it
force - (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 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); "the compressed gas exerts an increased pressure"
reflexion, reflection - 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
resolving power, resolution - 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
