2. Power (physics) - Wikipedia

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

   Power is the rate with respect to time at which work is done; it is the time derivative of work: =, where P is power, W is work, and t is time. We will now show that the mechanical power generated by a force F on a body moving at the velocity v can be expressed as the product: P = d W d t = F ⋅ v {\displaystyle P={\frac {dW}{dt}}=\mathbf {F ...

3. Mechanical energy - Wikipedia

   en.wikipedia.org/wiki/Mechanical_energy

   The difference between a conservative and a non-conservative force is that when a conservative force moves an object from one point to another, the work done by the conservative force is independent of the path. On the contrary, when a non-conservative force acts upon an object, the work done by the non-conservative force is dependent of the path.

4. Work (thermodynamics) - Wikipedia

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

   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.

5. Work (electric field) - Wikipedia

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

   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 .

8. Abstract labour and concrete labour - Wikipedia

   en.wikipedia.org/wiki/Abstract_labour_and...

   Abstract labour and concrete labour refer to a distinction made by Karl Marx in his critique of political economy.It refers to the difference between human labour in general as economically valuable worktime versus human labour as a particular activity that has a specific useful effect within the (capitalist) mode of production.
