Physics

Items

• equivalent

  Equal in value, amount, or effect.
• evaporation

  The process by which molecules at the surface of a liquid gain enough energy to enter the gas phase, even below the liquid's boiling point.
• exact

  Something is completely correct or precise, with no error or approximation.
• example

  A specific case or instance used to illustrate a principle, rule, or phenomenon in scientific study.
• exothermic

  A type of chemical or physical reaction that releases heat to its surroundings.
• expansion

  An increase in volume or size, often due to heat (thermal expansion) or a decrease in pressure.
• experiment

  A controlled procedure carried out to test a hypothesis, observe a phenomenon, or demonstrate a known fact.
• explicit

  Clearly defined or stated with no room for confusion or interpretation, especially in scientific instructions or models.
• exponent

  A mathematical notation indicating the number of times a quantity is multiplied by itself; in science, often used in expressing large or small numbers in scientific notation.
• expressed

  Shown, represented, or described, often in terms of quantities, equations, or measurable characteristics (e.g., a gene is "expressed" when it produces a protein).
• factor

  A component or variable that contributes to a result or outcome in a scientific process or equation.
• FALSE

  A logical value indicating that a statement or proposition is not true; used in data processing, programming, and logic-based scientific models.
• ferromagnet

  A material that can be magnetized and retains its magnetism in the absence of an external magnetic field (e.g., iron, cobalt, nickel).
• fibre

  A slender, thread-like structure, either natural (e.g., plant cellulose, muscle fibers) or synthetic, used in materials science and biology.
• field

  A region in which a particular force or influence (like gravitational, electric, or magnetic) is exerted on objects.
• figure

  A graphical or pictorial representation of data, concepts, or models, commonly used in scientific papers and reports.
• filament

  A thin wire or thread-like structure, often found in light bulbs (as a heat emitter) or biological structures (like actin filaments in cells).
• film

  A very thin layer of material, often used in scientific contexts like semiconductors, optics, or chemistry (e.g., thin films in solar cells).
• filter

  A device or process that removes unwanted components from a substance or signal, commonly used in optics, electronics, and chemistry.
• final

  Describes the end state or condition of a system after a process, such as final velocity, final temperature, etc.
• fission

  A nuclear reaction o r radioactive decay process in which the nucleus of an atom splits into smaller parts, releasing energy.
• flow

  The movement of a fluid or particles from one location to another, often described by velocity and volume rate.
• fluid

  A substance that can flow and take the shape of its container; includes both liquids and gases.
• fluorescent

  Describes a material that emits visible light when exposed to ultraviolet (UV) or other forms of electromagnetic radiation.
• flux

  The rate of flow of a quantity (e.g., magnetic flux, heat flux) through a surface or system.
