Why work done on the system is negativeand it is positive when its done by the system?
Oh, dude, it's like this: when work is done on the system, it's like the system is just chilling and getting stuff done to it, so it's negative because it's like, "Ugh, why are you messing with me?" But when the system does work, it's like, "Yeah, I got this," so it's positive because it's like, "I'm in control, baby!" So, yeah, that's why it's negative when done on the system and positive when done by the system.
What else can I help you with?
If a process is carried out at constant pressure P and the volume V of the system decreases then V is negative positive and the work w is negative positive zero?
In this case, V would be negative, and work w would be positive.
When work is positive and when is negative?
when work is positive and when playing is negative
Can work positive or Negative in physics how?
Yes Work can be positive or Negative.
How can you have both positive and negative work at the same time?
Very interesting approach! When Paul presses a spring then work done by Paul is positive and work performed by spring is negative. As per scalar product we have to use cos@ If @ is acute then cos @ is +ve and if @ is obtuse then it becomes -ve As force applied and displacement are in the same direction as in the case of Paul's attempt then work becomes positive But in case of spring's opposing force the displacement is in opposite direction and so work is negative
What are positive and negative work ethics?
what is positive and negative
Is the work done by the system is considered as positive or on the system is considered as positive?
In thermodynamics, work done by the system is considered positive. Work done on the system is considered negative.
How do you determine a work done is positive sign or negative sign?
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.
Is the work done on a system positive or 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.
What is the work done by the system according to the sign convention?
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 is?
work done on the system: when a surrounding does work on the system the total energy increases so work done is positive..........
When is positive work done in a physical system?
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.
When is a thermodynamic work said to be positive?
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.
When do you say that the work done is positive or negative?
Work done is considered positive when the force applied and the displacement of the object are in the same direction, causing movement in that direction. On the other hand, work done is considered negative when the force applied and the displacement are in opposite directions, resulting in work being done against the direction of the force.
What is the significance of the work done on the system in relation to the sign convention?
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 is work done positive?
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.
What is positive work done?
POSITIVE work is done when the direction of displacement and gravitational force is same. This makes an angle of zero degrees. Fd?FScos0 equals +1. The work done is positive.
When swimming work done is positive or negative?
Positive.
