Vocabulary for IELTS Academic (Band 8-9)

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

Ex: Everyday devices , such as electric motors and transformers , operate based on principles derived from electromagnetism .

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

Ex: The study of pneumatics is crucial for designing and optimizing systems that rely on compressed air for various engineering applications .

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

Ex: X-ray diffraction is a technique that utilizes the diffraction of X-rays to determine the structure of crystalline materials .

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

Ex: Extra dimensions beyond the familiar three space dimensions and one time dimension are required in string theory .
quark [noun]

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

Ex: Quarks possess fractional electric charges , making them a unique class of elementary particles .
lepton [noun]

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

Ex: Leptons are fundamental building blocks of matter and play a crucial role in the particle zoo described by the Standard Model .
hadron [noun]

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

Ex: The study of hadrons is essential for understanding the behavior of quarks within the framework of quantum chromodynamics ( QCD ) .
velocity [noun]

the speed at which something moves in a specific direction

Ex: In physics , velocity is a vector quantity that includes both speed and direction .

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

Ex: The amplitude of an electromagnetic wave determines the intensity of light or electromagnetic radiation .
fermion [noun]

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

Ex: Fermions follow specific rules called Fermi-Dirac statistics , governing how they can occupy quantum states .
boson [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

Ex: Bosons are named after Satyendra Nath Bose , an Indian physicist who made significant contributions to their statistical behavior .

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

Ex: When a car turns around a curve , the frictional force between the tires and the road provides the centripetal force .
coulomb [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

Ex: In practical terms , a coulomb represents a fundamental quantity of electric charge .

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

Ex: In astronomy , the Doppler effect helps scientists determine the speed and direction of celestial objects .

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

Ex: As a thrown ball rises and falls , its kinetic energy changes with its speed and position .
