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

• Does this answer your question? Why does work equal force times distance? – Thomas Fritsch Jan 22 '20 at 23:20
• Note that you do not derive definitions experimentally. They are just defined – BioPhysicist Jan 22 '20 at 23:23
• 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. – probably_someone Jan 22 '20 at 23:33
