مفردات لاختبار IELTS Academic (الدرجة 8-9) - Physics

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

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

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

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

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

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

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

the speed at which something moves in a specific direction

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

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

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

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

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

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 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
