electromagnetism

a branch of physics that studies the relationship between electric and magnetic fields, encompassing the electromagnetic force and electromagnetic interactions

électromagnétisme, magnétisme électrique

électromagnétisme, magnétisme électrique

Ex: The study of electromagnetism is integral to understanding the nature of light, electricity, and magnetism in the universe. 
pneumatics

a branch of engineering and physics that deals with the mechanical properties of gases, especially air, and the application of pressurized air to produce motion or mechanical effects

pneumatique, la pneumatique

pneumatique, la pneumatique

Ex: Pneumatics is commonly used in industries for operating tools and machinery using compressed air. 
diffraction

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

diffraction, diffraction des ondes

diffraction, diffraction des ondes

Ex: Diffraction of light produces patterns of alternating dark and bright regions when it encounters a narrow slit or passes through an obstacle. 
string theory

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

théorie des cordes, théorie des supercordes

théorie des cordes, théorie des supercordes

Ex: String theory proposes that the basic building blocks of the universe are tiny, vibrating strings rather than point-like particles. 
quark
quark
[nom]

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

quark, quark (particule élémentaire)

quark, quark (particule élémentaire)

Ex: Quarks are the smallest known particles, forming the building blocks of protons and neutrons in atomic nuclei. 
lepton
lepton
[nom]

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

lepton, particule élémentaire de spin demi-entier

lepton, particule élémentaire de spin demi-entier

Ex: Leptons are elementary particles that include electrons, muons, tau particles, and their associated neutrinos. 
hadron
hadron
[nom]

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

hadron, particule hadronique

hadron, particule hadronique

Ex: Hadrons are subject to the strong nuclear force, the fundamental interaction that binds quarks together. 
velocity

the speed at which something moves in a specific direction

vitesse

vitesse

Ex: The velocity of an object is the rate of change of its position with respect to time. 
amplitude

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

amplitude

amplitude

Ex: In physics, amplitude refers to the maximum displacement of a wave from its equilibrium position. 
fermion
fermion
[nom]

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

fermion, particule de Fermi

fermion, particule de Fermi

Ex: Electrons, which orbit the nucleus of an atom, are examples of fermions. 
boson
boson
[nom]

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

boson, particule de spin entier

boson, particule de spin entier

Ex: Photons, particles of light, are examples of bosons that carry the electromagnetic force. 
centripetal force

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

force centripète, force de rappel vers le centre

force centripète, force de rappel vers le centre

Ex: When you swing a ball attached to a string in a circular motion, the tension in the string acts as the centripetal force. 
coulomb
coulomb
[nom]

the unit of electric charge in the International System of Units (SI), equal to the charge transported by a constant current of one ampere in one second

coulomb, le coulomb

coulomb, le coulomb

Ex: One coulomb is equivalent to the charge transported by a current of one ampere in one second. 
doppler effect

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

effet Doppler, phénomène Doppler

effet Doppler, phénomène Doppler

Ex: The Doppler effect explains why the pitch of an ambulance siren changes as it approaches and then passes by. 
kinetic energy

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

énergie cinétique, énergie de mouvement

énergie cinétique, énergie de mouvement

Ex: When a car is in motion, its kinetic energy depends on both its mass and speed.
