Naturvetenskap SAT - Elektromagnetism och mekanik

the measure of electric potential difference between two points in a circuit, expressed in volts

spänning

an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance

resistor

the complete circle through which an electric current flows, typically consists of the source of electric energy

elektrisk krets

a solid substance that conducts electricity or heat better than insulators, but not as well as most metals

halvledare

a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures

supraledning

to apply an electric charge to a conductor

elektrifiera

a conductor through which electricity travels to or from an object, such as batteries

elektrod

a form of electricity generated by friction between two materials, resulting in an imbalance of electric charges on their surfaces

statisk elektricitet

(of a battery or device) capable of being supplied with electrical power again

uppladdningsbar

a machine that produces electricity by converting mechanical energy into electrical energy

generator

a positively charged electrode in an electrical device where oxidation occurs, resulting in the release of electrons

anod

a negatively charged electrode within an electrical device, from which electrons flow out into the external circuit

katod

a device that converts the energy of the sun into electricity

solcell

the amount of solar energy received per unit area on Earth's surface

solirradians

the energy transmitted in the form of particles or waves through the space or a matter

strålning

related to the technology that turns sunlight directly into electricity

fotovoltaisk

referring to the combined interaction of electric and magnetic fields, often associated with waves or radiation

elektromagnetisk

an invisible area around a magnetic object where magnetic forces can attract or repel other objects

magnetfält

a long rigid bar that is put under a heavy object in order to move it

hävarm

a point or support on which a lever pivots or rotates in order to lift or move objects

pivot

the rapid back-and-forth movement of an object

vibration

a rotational force measured in newton-meters or foot-pounds

moment

a measure of a spring's stiffness, indicating how much force is needed to stretch or compress it

fjäderkonstant

a mass used to provide balance to another mass

motvikt

having a speed greater than that of sound

supersonisk

(physics) the increase in velocity over time

accelerationen

the constant speed reached by a falling object when the drag force equals the gravitational force pulling it downward, resulting in no further acceleration

terminalhastighet

the study of the design, development, and operation of aircrafts, focusing on principles of aerodynamics, propulsion, and material science

luftfart

a branch of science and engineering that deals with the mechanical properties of liquids, particularly their behavior in confined spaces and under pressure

hydraulik

an area of technology that is concerned with the study or use of robots

robotik

(physics) the universal force of attraction between any pair of objects with mass
