Answer to Problem 1Q
Solution:
In physics, work is done when a net force is applied to an object and it moves, whereas in everyday language it is not always so.
Explanation of Solution
The word “work” in everyday language refers to a work activity performed by an employee or some human activity, for example: ”I go to work “, ”I have a lot of work to do “or, ”I do not like that job “. In contrast, the concept of physics work refers to the product of the magnitude of the displacement by the component of the force parallel to displacement. This means that, in physics, work is done when a force is applied and the object is displaced. For example, a man who pushes a heavy box to the right with a force F so that the box moves a distance x, here in physics: “work” is done and in everyday language, the job of this man is like word “work” in physics. On the other hand, suppose another man whose job (work in everyday language)is to hold boxes with his hands without moving, from the point of view of physics no work is done on the box since there is no displacement.
