Physics Categories.
Canadian Medical Guide Definition Acoustics - The branch of physics that deals with sound and sound waves. In medicine it is often applied in procedures in speech and hearing studies. With regard to the environment, it refers to the characteristics of a room, auditorium, theatre, building, etc. that determines the audibility or fidelity of sounds in it. (From Random House Unabridged Dictionary, 2d ed)
Canadian Medical Guide Definition Doppler Effect - Changes in the observed frequency of waves (as sound, light, or radio waves) due to the relative motion of source and observer. The effect was named for the 19th century Austrian physicist Johann Christian Doppler.
Canadian Medical Guide Definition Gravitation - Acceleration produced by the mutual attraction of two masses, and of magnitude inversely proportional to the square of the distance between the two centers of mass. It is also the force imparted by the earth, moon, or a planet to an object near its surface. (From NASA Thesaurus, 1988)
Canadian Medical Guide Definition Hardness
Canadian Medical Guide Definition Lubrication - The application of a substance to diminish friction between two surfaces. It may refer to oils, greases, and similar substances for the lubrication of medical equipment but it can be used for the application of substances to tissue to reduce friction, such as lotions for skin and vaginal lubricants.
Canadian Medical Guide Definition Magnetics - The study of magnetic phenomena and magnetic fields. Magnetism produced by electric currents is ELECTROMAGNETICS.
Canadian Medical Guide Definition Mechanics - The branch of physics which deals with the motions of material bodies, including kinematics, dynamics, and statics. When the laws of mechanics are applied to living structures, as to the locomotor system, it is referred to as BIOMECHANICS. (From Dorland, 28th ed)
Canadian Medical Guide Definition Motion - Physical motion, i.e., a change in position of a body or subject as a result of an external force. It is distinguished from MOVEMENT, a process resulting from biological activity.
Canadian Medical Guide Definition Nuclear Physics
Canadian Medical Guide Definition Optics
Canadian Medical Guide Definition Porosity - Condition of having pores or open spaces. This often refers to bones, bone implants, or bone cements, but can refer to the porous state of any solid substance.
Canadian Medical Guide Definition Pressure
Canadian Medical Guide Definition Radiation - Emission or propagation of electromagnetic energy (waves/rays), or the waves/rays themselves; a stream of electromagnetic particles (electrons, neutrons, protons, alpha particles) or a mixture of these. The most common source is the sun.
Canadian Medical Guide Definition Thermal Conductivity
Canadian Medical Guide Definition Thermodynamics - A rigorously mathematical analysis of energy relationships (heat, work, temperature, and equilibrium). It describes systems whose states are determined by thermal parameters, such as temperature, in addition to mechanical and electromagnetic parameters. (From Hawley's Condensed Chemical Dictionary, 12th ed)
