the complete circle through which an electric current flows, typically consists of the source of electric energy
circuit electric, circuit
a solid substance that conducts electricity or heat better than insulators, but not as well as most metals
semiconductor, substanță semiconductor
a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures

supersonic, suprasonic
(physics) the increase in velocity over time
accelerație, accelerare
the constant speed reached by a falling object when the drag force equals the gravitational force pulling it downward, resulting in no further acceleration
viteza terminală, viteza maximă de cădere
the study of the design, development, and operation of aircrafts, focusing on principles of aerodynamics, propulsion, and material science
aviatie, aeronautica
a branch of science and engineering that deals with the mechanical properties of liquids, particularly their behavior in confined spaces and under pressure
