In thermodynamics, positive work is done on a system when energy is transferred from an external source to the system, resulting in an increase in the system's energy. Negative work, on the other hand, is done by a system when energy is transferred from the system to an external source,...
In physics, the term work refers to the transference of energy that occurs when a force is applied to a body that is moving in such a way that the force has a component in the direction of the body's motion. Thus work is done on a weight that is being lifted, or on a spring tha...
In other words, the system does work on the surroundings, or positive work is done by the system rather than on the system. If a gas compresses, things are the other way around. In thermodynamics, one adopts a definition of "work" and specifies whether it is positive...

In thermodynamics, adiabatic processes are those where no heat exchange takes place between the work substance and the environment. Adiabatic processes can be classified in: {eq}\bullet {/eq} Reversible, satisfying the polytropic equation, {eq}pV^\gamma=C {/eq}, where {eq}\gamma=c_p/c_v...
An example where much work is done on stretching the adhesive is a pressure sensitive adhesive which forms filaments before the adhesive detaches. If the phases are separated in dry air, work of adhesion WA is given by Eq. (30). (30)WA=γA+γS−γAS But if separation is in the ...
whenever work is done, energy is transferred. for a work to be done, in a scientific sense, a force must be exerted, and there must be displacement in the direction of the force. with this said, we can say that work is the product of the component of the force in the direction...
The net work is equal to the change in kinetic energy. I'm going to take the area under the curve for this whole entire graph here up until , and then I'm going to relate that to . I'm going to break this up into a couple of sections. The work done from 0 to 2, plus the...
