Listă de Cuvinte Nivel C2 - Physics

a scientific idea that all particles are tiny vibrating strings, not point-like dots, and these vibrations create different particles and forces

teoria stringurilor, teoria sorților

the bending, spreading, and interference of waves as they encounter obstacles or pass through narrow openings, often observed in the behavior of light, sound, or other waves

difracție

a fundamental particle combining to form protons and neutrons, with fractional electric charge and six flavors

quark

a fundamental particle with half-integer spin, including electrons and their heavier counterparts, as well as neutrinos

lepton, particulă leptonică

a tiny particle made up of even smaller parts called quarks, like protons and neutrons

hadron

the speed at which something moves in a specific direction

viteza, celeritate

(physics) the maximum distance a vibrating material, sound wave, etc. such as a pendulum travels from its first position

amplitudine

tiny particles that make up matter and have a property called spin, like the building blocks of atoms

fermion

a tiny particle with whole-number spin, such as photons or the Higgs boson, often associated with carrying fundamental forces or giving mass to other particles

bozon

the force that acts on an object moving in a circular path, directed toward the center of the circle or the axis of rotation, preventing the object from moving in a straight line

forța centripetă, forța de centru

the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the source of the wave, producing a shift in pitch or color

efectul Doppler, efect Doppler

the energy possessed by an object due to its motion, defined as one-half the mass of the object multiplied by the square of its velocity, expressed by the equation KE = 0.5 * m * v^2

energie cinetică, energie de mișcare

(physics) an invisible substance that makes up most of the universe's mass, detectable only through its gravitational effects

materie întunecată, materie noiră

(physics) matter consisting of elementary particles that are the antiparticles of those of regular matter

antimaterie

(physics) the property of matter that gives it weight in a gravitational field and is a measure of its inertia

masă, masă (fizică)

the smallest possible amount of a particular quantity that cannot be divided any further

cuant, cantitate minimă

(physics) the increase in velocity over time

accelerație

the strength of a moving object determined by multiplying how heavy it is by how fast it is going

moment, impuls

a fundamental particle of light that carries electromagnetic energy and exhibits both particle-like and wave-like properties

foton

the tendency of an object to resist changes in its state of motion, whether at rest or in uniform motion, and to remain in its current state unless acted upon by an external force

inerție

(physics) the back-and-forth motion of an object between two end points

oscilație, oscilație armonică

the action or process where a wave, such as light or sound, bounces back from a surface instead of passing through

reflexie, răsfrângere

a measure of a material's stiffness or elasticity in physics

modul Young, modul de elasticitate

a theory stating that the exact position and momentum of a particle cannot be measured precisely at the same time

principiul incertitudinii

the unit of energy in the International System of Units

joule

a very small, electrically neutral particle that rarely interacts with matter

neutrino

the theory that adds the notion of time to that of a three-dimensional space

spațiu-timp, timp-spațiu

the process or action of splitting a nucleus into two or more parts resulting in the release of a significant amount of energy

fisiune nucleară, împărțirea nucleului

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

electromagnetic

(physics) the reaction in which two nuclei join together and produce energy

fuziune nucleară, fuziunea nucleelor
