(Greek: power, strength, force, mightiness)

1. A device for automatically registering muscular power.
2. An instrument for recording the degree of muscular force.
1. A modified stethoscope for auscultation (listening for sounds) of the muscles.
2. An instrument for observing functional activities usually taking place within the body.
An apparatus for inducing diathermy.
1. A vacuum tube device which has three electrodes: a thermionic cathode, a perforated anode, and a supplementary anode or plate.
2. A multi-electrode thermionic valve often used as an oscillator.
1. The study of the relationships between electromagnetic and mechanical phenomena.
2. A branch of physics that studies how electric currents interact with magnetic and mechanical force including the the mutual influence of electric currents, the interaction of currents and magnets, and the influence of an electric current on itself.
3. The study of electrostatic charges in motion; such as, the flow of electrons in an electric current.
4. The science of energy transformations as related to electric currents and their magnetic fields.
1. Fluid dynamics applied to liquids; such as, water, alcohol, oil, and blood.
2. The branch of science that deals with the dynamics of fluids; especially, incompressible fluids, in motion.
3. The dynamics of fluids in motion.
4. The branch of fluid dynamics that deals with liquids, including hydrostatics and hydrokinetics. Also called hydromechanics.
5. A branch of physics that deals with the motion of fluids and the forces acting on solid bodies immersed in fluids and in any motion relative to them.

The science of mechanics which relates to fluids or which deals with the laws of motion and action of nonelastic fluids, whether as investigated mathematically, or by observation and experiment; the principles of dynamics, as applied to water and other fluids.

The word is sometimes used as a general term, including both hydrostatics and hydraulics, together with pneumatics and acoustics.

A reference to nervous energy.
