What else can I help you with?
Is the work done by the system is considered as positive or on the system is considered as positive?
Work done by the system is considered as PositiveWork done on the system is considered as 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.
When swimming work done is positive or negative?
Positive.
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.
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 do you say that the work done is positive or negative?
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.
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..........
What would happen to an object's velocity if positive work was done on an object?
If positive work is done on an object, its velocity will increase. This is because work done on an object transfers energy to the object, which can result in an increase in its kinetic energy and thus its velocity.
When the force acting on an objects points at least partially in the blank direction of the motion the work done is considered to be what?
When the force acting on an object points at least partially in the direction of motion, the work done is considered to be positive. This is because the force is helping to move the object in the same direction as its motion, resulting in a positive work output.
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.
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.
