Work in Science

The day-to-day use of the term 'work' may refer to hard effort, while the scientific definition of work involves the displacement of an object by a force.

Kamali's activities such as reading, drawing diagrams, and attending classes may involve expending energy, but if there is no displacement of objects involved, it may involve very little 'work' according to the scientific definition.

The example of pushing a huge rock without it moving despite the effort illustrates the difference between 'working hard' and the scientific definition of work.
