When can you say that the work is not done?

You can say the work is not done when the desired outcome or goal has not been achieved or completed. This could be due to remaining tasks, missing components, or unresolved issues that prevent the work from being considered complete.


Where do you say that work is done an object?

Work is done on an object when a force is applied to the object and the object moves in the direction of the force. The work done is calculated as the product of the force applied and the distance the object moves in the direction of the force.


When do you say that work is done?

Work is considered done when all the tasks and objectives set out in a project or assignment have been completed satisfactorily, meeting the predetermined criteria and specifications. It signifies successful accomplishment and achievement of the desired outcomes.


How can you find the initial velocity form the work done on a system?

To find the initial velocity from the work done on a system, you can use the work-energy principle. The work done on the system is equal to the change in kinetic energy of the system. By equating the work done to the change in kinetic energy and solving for the initial velocity, you can find the initial velocity of the system.


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.
