  2. Work (physics) - Wikipedia

    en.wikipedia.org/wiki/Work_(physics)

    In science, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled. A force is said to do positive work if it has a component in the ...

  3. Scientific method - Wikipedia

    en.wikipedia.org/wiki/Scientific_method

    e. The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century. The scientific method involves careful observation coupled with rigorous scepticism, because cognitive assumptions can distort the interpretation of the observation.

  4. Scientific theory - Wikipedia

    en.wikipedia.org/wiki/Scientific_theory

    A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. The theory of biological evolution is more than "just a theory".

  5. Work (human activity) - Wikipedia

    en.wikipedia.org/wiki/Work_(human_activity)

    Work or labor (or labour in British English) is the intentional activity people perform to support the needs and wants of themselves, others, or a wider community. [ 1] In the context of economics, work can be viewed as the human activity that contributes (along with other factors of production) towards the goods and services within an economy.

  6. Work (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Work_(thermodynamics)

    t. e. Thermodynamic work is one of the principal processes by which a thermodynamic system can interact with its surroundings and exchange energy. This exchange results in externally measurable macroscopic forces on the system's surroundings, which can cause mechanical work, to lift a weight, for example, [ 1] or cause changes in ...

  7. Work function - Wikipedia

    en.wikipedia.org/wiki/Work_function

    Work function. In solid-state physics, the work function (sometimes spelled workfunction) is the minimum thermodynamic work (i.e., energy) needed to remove an electron from a solid to a point in the vacuum immediately outside the solid surface. Here "immediately" means that the final electron position is far from the surface on the atomic scale ...

  8. Scientific management - Wikipedia

    en.wikipedia.org/wiki/Scientific_management

    Scientific management is a theory of management that analyzes and synthesizes workflows. Its main objective is improving economic efficiency, especially labor productivity. It was one of the earliest attempts to apply science to the engineering of processes to management. Scientific management is sometimes known as Taylorism after its pioneer ...

  9. Science - Wikipedia

    en.wikipedia.org/wiki/Science

    Science is a strict systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the world. [1] [2] Modern science is typically divided into three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study ...
