lepton/lˈɛptən/noun
a fundamental particle with half-integer spin, including electrons and their heavier counterparts, as well as neutrinos
"Electrons are a type of lepton."
"A lepton is a fundamental particle with half-integer spin, including electrons and their heavier counterparts."
hadron/ˈhæˌdɹɔn/noun
a tiny particle made up of even smaller parts called quarks, like protons and neutrons
"Protons and neutrons are hadrons."
"A hadron is a composite particle made of quarks bound by the strong force"
velocity/vəˈɫɑsəti/noun
the speed at which something moves in a specific direction
"The car's velocity increased quickly."
"The car was traveling at a dangerous velocity when it crashed into the tree on the roadside."
amplitude/ˈæmpɫəˌtud/noun
(physics) the maximum distance a vibrating material, sound wave, etc. such as a pendulum travels from its first position
"The amplitude of the sound wave determines how loud the noise is."
"Amplitude is the maximum extent of a wave's displacement from its equilibrium position"
fermion/ˈfɜrmiˌɒn/noun
tiny particles that make up matter and have a property called spin, like the building blocks of atoms
"Electrons are examples of fermions."
"Every fermion in the universe follows a special rule about sharing energy levels."
boson/bˈɑːsən/noun
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
"Photons are examples of bosons."
"A boson is a force-carrying particle that obeys Bose-Einstein statistics"
centripetal force/sˈɛntɹaɪptəl fˈoːɹs/noun
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
"Centripetal force keeps planets in orbit."
"Centripetal force is the inward-directed force required to keep an object moving in a curved path"
coulomb/kˈuːlɑːm/noun
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
"A coulomb measures electric charge."
"A coulomb is the SI unit of electric charge"
doppler effect/dˈɑːplɚɹ ɪfˈɛkt/noun
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
"The Doppler effect changes sound pitch."
"The Doppler effect is the change in observed frequency of a wave when the source and observer are moving relative to each other."
kinetic energy/kᵻnˈɛɾɪk ˈɛnɚdʒi/noun
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
"Moving objects have kinetic energy."
"Kinetic energy is the energy an object possesses due to its motion"
