Meter is a unit of measurement and a device that measures like distance or flow, as well as a rhythmic pattern in poetry or music. In everyday use it denotes the instrument or standard for gauging quantity, time, or intensity, and can refer to the rhythm scheme of a poem or song. It commonly appears in technical, poetic, and literary contexts.

Motor (noun) refers to a device or mechanism that produces motion in a machine or system, or the driving part of a vehicle. It can also denote the active force that causes movement in an object. In everyday use, it often contrasts with a generator or brake, emphasizing propulsion or power source.

Nozzle is a narrow mouth or passage through which a fluid is directed or emitted, often tapering to a small opening. It functions to control flow, pressure, and direction, as in a hose, candle nozzle, or rocket engine. The term can also refer to a projecting mouthpiece on devices that release liquids, gases, or powders, shaping the spray or jet.

Optimization is the process of making something as effective or functional as possible, often by adjusting parameters to improve performance. In practice, it involves identifying constraints, evaluating options, and applying systematic methods to achieve best results. The term spans mathematics, computer science, engineering, and business contexts, and can refer to both algorithmic efficiency and resource utilization.

Plastic is an adjective describing materials made from synthetic polymers, or something malleable and easily shaped like a moldable substance. In common usage, it also characterizes something superficial or fabricated, lacking lasting value. The term covers both physical material (plastic toys, plastic bottles) and figurative senses (plasticity of memory), and is frequently found in technical, design, and consumer contexts.

Plate is a flat, typically circular dish used for serving or eating food. As a noun, it also denotes a flat support or a plate-like object; in geology, a tectonic plate is a section of the Earth's lithosphere. The word is concise, widely used in dining, cooking, and science contexts, with a crisp, single-syllable release.

Polymer is a noun for a substance composed of many repeating units, typically molecules or monomers joined into long chains. It denotes a material with high molecular weight formed by polymerization processes, often plastics or resins, that display distinct physical properties such as elasticity or durability. The term is used broadly in chemistry, materials science, and industry to describe these large, chain-like macromolecules.

Polynomial is a noun referring to an algebraic expression composed of multiple terms, each a constant multiplied by a variable raised to a nonnegative integer power. It is a fundamental concept in algebra and calculus, used to describe shapes, functions, and equations. In common usage, a polynomial can be as simple as a linear expression or as complex as a high-degree polynomial with many terms.

Potential is an adjective describing something with latent capability or possibility. It denotes the capacity for growth, development, or future achievement, and is often used to qualify people, ideas, or situations that could become more significant under the right conditions.

Power as a noun refers to the capacity or ability to act, influence, or produce an effect. It can describe physical strength, political clout, or the operational capability of machines. In everyday usage, it often conveys potential energy, control, or dominance within a system or relationship.

Pressure (n.) refers to the force per unit area exerted on an object, or the influence that causes a person to act or perform. It can be physical, social, emotional, or psychological, and may arise from constraints, expectations, or urgency. In everyday use, it describes both tangible pressure in material contexts and intangible pressure in decision-making or performance scenarios.

Propulsion is the act or system that drives something forward, typically by a force such as thrust or motive power. It refers to the mechanism or process that causes forward movement, in engines, vehicles, or biological organisms. In engineering and physics contexts, propulsion discusses how energy is converted to motion and direction.

Pulley is a simple machine consisting of a wheel with a grooved rim that holds a rope or belt. It enables lifting or changing the direction of a force with less effort, often used in systems of blocks and tackle. As a noun, it also refers to the wheel itself or the mechanism’s assembly.

Radius is a noun meaning a line segment from the center of a circle or sphere to any point on its circumference, or the corresponding distance. It also appears in anatomy as a forearm bone. The term encompasses geometric, mathematical, and anatomical senses, and is used in contexts ranging from geometry proofs to medical descriptions.

Reliability is the quality of being trustworthy and consistent, indicating that something performs as expected over time. It implies dependability, steadiness, and a predictable outcome under normal conditions. In technical contexts, reliability often refers to the probability that a system will function without failure for a specified period.

Resonance is the quality of a sound that is amplified or deepened by vibrating objects around or inside the source, producing a fuller, more reverberant tone. It also refers to the collective effect of repeated or persistent vibrations within a system, influencing its overall character. In acoustics and physics, resonance occurs when a system responds with maximum amplitude at a particular frequency.

Rivet is a short, crisp tool- or fastener-shaped noun used in joining metal parts. It also refers to a metal fastener driven through holes and clinched to hold pieces together. In figurative use, it can mean something that captures attention or interest strongly. The word emphasizes a compact, hard-edged sound, often heard in technical or industrial contexts.

Rod is a short, singular spear-like or cylindrical tool or bar, commonly used as a fishing tool, a support, or a measure. It can also refer to a staff or rod-like object in various contexts. The term conveys a solid, slender, straight form and is often used in everyday language as a concrete noun with practical applications.

Screw (noun) refers to a slender, threaded fastener with a slotted head that is driven into materials to hold them together or secure objects. It can also describe a turn of the tool applied to rotate the fastener. In slang, “screw” can mean to cheat or to twist something out of shape. The term is widely used in engineering, construction, and everyday hardware discussions.

Shear (noun) refers to a cut or stroke made with a blade, such as in shearing wool, or a mechanical process that slices material. It can also denote a thin layer or strip separated by a cutting action. In geology, it describes a fracture surface produced by shear stress, while in farming it describes the event of clipping livestock. The term emphasizes the act of cutting or slippage along a plane.

Solder (noun) refers to a fusible metal alloy used to join pieces of metal together by melting and flowing into the joint. It also describes the joint itself formed by this process. The term is common in electronics, plumbing, and metalwork, and the spelling variation 'soldier' is a frequent homograph, though unrelated in meaning.

Spline is a smooth, flexible curve used in mathematics and computer-aided design to interpolate data points. In everyday math, it often refers to a polynomial function that passes through several points with a gentle, continuous bend. In engineering and graphics, splines create smooth shapes and transitions, avoiding sharp corners.

Stability is the quality or state of being stable and not easily changed or moved, especially in a way that provides reliability and safety. As a noun, it refers to steadiness in physical balance, emotional composure, or systems that resist disruption. In contexts like engineering, psychology, and everyday life, stability denotes enduring predictability and resilience against perturbation.

Telemetry is the science and technology of recording, transmitting, and analyzing measurements from a distance. It typically involves sensors, data channels, and telemetry systems that convey real-time or stored information for monitoring and control purposes across remote locations.
