Vocabulary for IELTS Academic (Band 6-7)

resistor [noun]

an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance

Ex: The color-coded bands on resistors indicate their resistance value , tolerance , and sometimes temperature coefficient .

capacitor [noun]

an electric device that is used to accumulate electric charge

thermodynamics [noun]

the branch of physical science that deals with the relationships between heat, work, and energy, particularly the principles governing the conversion of various forms of energy

Ex: The second law of thermodynamics introduces the concept of entropy , indicating that natural processes tend to increase disorder in a closed system .

dark matter [noun]

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

Ex: Despite extensive research efforts , the true nature of dark matter remains one of the biggest mysteries in astrophysics .

photon [noun]

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

Ex: The dual nature of photons is described by wave-particle duality , a fundamental concept in quantum mechanics .

frequency [noun]

the specific number of waves that pass a point every second

Ex: The radio station broadcasts at a frequency of 101.5 megahertz .

wavelength [noun]

the distance between a point on a wave of energy and a similar point on the next wave

Ex: The wavelength of a radio wave determines its frequency and how it interacts with antennas .

reflection [noun]

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

Ex: The calm lake 's surface served as a perfect mirror , providing a clear reflection of the surrounding mountains .

momentum [noun]

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

Ex: The cyclist 's momentum helped him climb the steep hill .

inertia [noun]

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

Ex: In space , where there is no air resistance , an object set in motion will continue moving indefinitely due to its inertia .

oscillation [noun]

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

Ex: Gravitationally bound binary star systems undergo regular orbital oscillations as the pair revolve around their mutual center of mass .

transistor [noun]

a small semiconductor device, used in television and radio sets, able to amplify or rectify an electric current

diode [noun]

an electronic device with two terminals, typically allowing the flow of current in one direction only

inductor [noun]

an electronic component that stores energy in a magnetic field when an electric current flows through it; typically consists of a coil of wire

Ex: Transformers utilize inductors to transfer electrical energy between different circuits by inducing a changing magnetic field in a nearby coil .

aerodynamics [noun]

the study of the behavior of air as it interacts with solid objects, particularly the flow of air around and through objects, and the effects of this interaction on the objects

Ex: Car manufacturers use aerodynamics to design vehicles that have improved fuel efficiency by minimizing drag and maximizing stability .
