The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...
Thermodynamic work is one of the principal kinds of process by which a thermodynamic system can interact with and transfer energy to its surroundings. This 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 electromagnetic, [2] [3] [4] or gravitational [5] variables.
Work, labor (labour in Commonwealth English), or an occupation or job is the intentional activity people perform to support the needs and desires of themselves, other ...
Work (electric field), the work done on a charged particle by an electric field; Work (thermodynamics), energy transferred by the system to its surroundings; Creative work, a manifestation of creative effort Work of art, an artistic creation of aesthetic value; Career, an individual's journey through learning, work and other aspects of life
The work function W for a given surface is defined by the difference [1] =, where −e is the charge of an electron, ϕ is the electrostatic potential in the vacuum nearby the surface, and E F is the Fermi level (electrochemical potential of electrons) inside the material.
The work per unit of charge is defined as the movement of negligible test charge between two points, and is expressed as the difference in electric potential at those points. The work can be done, for example, by generators, (electrochemical cells) or thermocouples generating an electromotive force.
Work ethic is a belief that work and diligence have a moral benefit and an inherent ability, virtue or value to strengthen character and individual abilities. [1] Desire or determination to work serves as the foundation for values centered on the importance of work or industrious work.
Work approved by; Description of completed work; Work completed by; Date of completion; In a manufacturing environment, a work order is converted from a sales order to show that work is about to begin on the manufacture, building or engineering of the products requested by the customer. In a service environment, a work order can be equivalent ...
