Why is the definition $\text{Work}= \text{Force}\cdot\text{Displacement}$ useful to describe the physical world?

Edit: Added another question as suggested by probably_someone, I think that this topic must also be covered to fully understand work

    $\begingroup$ Does this answer your question? Why does work equal force times distance? $\endgroup$ – Thomas Fritsch Jan 22 '20 at 23:20
  • $\begingroup$ Note that you do not derive definitions experimentally. They are just defined $\endgroup$ – BioPhysicist Jan 22 '20 at 23:23
  • $\begingroup$ I think there's a more interesting possibly-non-duplicate question that underpins this one: What makes this definition of work useful for describing nature? If that's the question you're asking, feel free to make that clear. $\endgroup$ – probably_someone Jan 22 '20 at 23:33
