Positive work is done in a physical system when the force applied to an object is in the same direction as the displacement of the object.
Work done by the system is considered as PositiveWork done on the system is considered as Negative
The work done on a system is positive when energy is added to the system, and negative when energy is removed from the system.
The work done by the system is positive if the system does work on its surroundings, and negative if work is done on the system by the surroundings.
work done on the system: when a surrounding does work on the system the total energy increases so work done is positive..........
Yes, work done can be negative in a physical system when the force applied is in the opposite direction of the displacement.

If work is done on the system then it has a negative sign. If work is done by the system then it has a positive sign.
The work done on a system is positive when energy is added to the system, and negative when energy is removed from the system.
The work done by the system is positive if the system does work on its surroundings, and negative if work is done on the system by the surroundings.

Yes, work done can be negative in a physical system when the force applied is in the opposite direction of the displacement.
A thermodynamic work is said to be positive when the system does work on the surroundings. This occurs when energy is transferred from the system to the surroundings, resulting in a decrease in the internal energy of the system.
First, there are certain sign conventions. It could be defined in a different way, but things are traditionally done in a certain way. Second, if work going out of the system is defined as positive, then it is quite logical that work going into a system should have the opposite sign.
There are different conventions as to what work is negative and what work is positive. The convention used by engineers and physicists is that work done BY the system on its surroundings is positive while work done ON the system by its surroundings is negative. Chemists reverse these conventions.
There are two conventions. One says that work done on the system is positive, the other says that work done by the system is positive. Chemists tend to use the former, physicists tend to use the latter... one of several reasons it's not a good idea to take thermodynamics in chemistry and physics at the same time.
The significance of the work done on the system in relation to the sign convention is that it helps determine whether work is being done on the system (positive work) or by the system (negative work). This understanding is crucial in analyzing the energy transfer within the system and its surroundings.
When a system does work on its surroundings, the sign of work is negative. This is because work done by the system involves energy leaving the system, which decreases its internal energy. In thermodynamics, this is typically represented as ( W < 0 ). Conversely, if work is done on the system by the surroundings, the work is considered positive.
