total potential energy provided by a power source
an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance
the complete circle through which an electric current flows, typically consists of the source of electric energy
a solid substance that conducts electricity or heat better than insulators, but not as well as most metals
a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures
to apply an electric charge to a conductor
a conductor through which electricity travels to or from an object, such as batteries
a positively charged electrode in an electrical device where oxidation occurs, resulting in the release of electrons
a negatively charged electrode within an electrical device, from which electrons flow out into the external circuit
a form of electricity generated by friction between two materials, resulting in an imbalance of electric charges on their surfaces
(of a battery or device) capable of being supplied with electrical power again
a machine that produces electricity by converting mechanical energy into electrical energy
a device that converts the energy of the sun into electricity
energy transmitted through space or matter in the form of waves or particles
related to the technology that turns sunlight directly into electricity
referring to the combined interaction of electric and magnetic fields, often associated with waves or radiation
an invisible area around a magnetic object where magnetic forces can attract or repel other objects
a long rigid bar that is put under a heavy object in order to move it
the rapid back-and-forth movement of an object
a point or support on which a lever pivots or rotates in order to lift or move objects
a rotational force measured in newton-meters or foot-pounds
a measure of a spring's stiffness, indicating how much force is needed to stretch or compress it
a mass used to provide balance to another mass
having a speed greater than that of sound
the study of the design, development, and operation of aircrafts, focusing on principles of aerodynamics, propulsion, and material science
(physics) the increase in velocity over time
the constant speed reached by a falling object when the drag force equals the gravitational force pulling it downward, resulting in no further acceleration
