e. 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 ...
PV work is often measured in units of litre-atmospheres where 1 L·atm = 101.325 J. However, the litre-atmosphere is not a recognized unit in the SI system of units, which measures P in pascals (Pa), V in m 3, and PV in joules (J), where 1 J = 1 Pa·m 3. PV work is an important topic in chemical thermodynamics.
Work unit. A work unit or danwei ( simplified Chinese: 单位; traditional Chinese: 單位; pinyin: dān wèi) is the name given to a place of employment in the People's Republic of China. The term danwei remains in use today, as people still use it to refer to their workplace. However, it is more appropriate to use danwei to refer to a place ...
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 ...
An energy unit that is used in atomic physics, particle physics and high energy physics is the electronvolt (eV). One eV is equivalent to 1.602 176 634 × 10−19 J. [ 2] In spectroscopy the unit cm −1 ≈ 0.000 123 9842 eV is used to represent energy since energy is inversely proportional to wavelength from the equation .
A work unit is the protein data that the client is asked to process. Work units are a fraction of the simulation between the states in a Markov model. After the work unit has been downloaded and completely processed by a volunteer's computer, it is returned to Folding@home servers, which then award the volunteer the credit points.
Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity. Mechanical power is also described as the time derivative of work.
The kilogram (kg) is the unit of mass. The ampere (A) is the unit of electric current. The kelvin (K) is the unit of thermodynamic temperature. The mole (mol) is the unit of amount of substance. The candela (cd) is the unit of luminous intensity. The SI also defines 22 derived units and associated symbols:
