This question already has an answer here:
I'm writing my first paper, so I'm unsure about the guidelines I should follow. The subject is within the field of mechatronics and computer simulation.
If I use some basic physics equation in it (say Newton's second law), should I always add some reference that validates this formula? Or such basic equations don't need to be validated?
If the answer to the above is no, then what if I introduce a lesser known physical model (such as Coulomb's friction model)? Should I then add some reference explaining it in detail to the reader?
