Classical Mechanics in High School

A Study of Particular Cases

Abstract

Apocryphal phrases attributed to Albert Einstein led physics teachers to always check their sources and correct erroneous interpretations of what Einstein said. This fact has prompted a similar reflection on the content taught in introductory courses in fundamental physics.
Indeed, how often is a physics subject taught by simply presenting the "formulas" without verifying or discussing their limitations or mentioning the implicit idealizations or the reason for their use?
Considering the teaching of the concept of force, here is a didactic verification of the more general contexts that culminate in some equations that make up the famous physics formulas. In other words, based on more general contexts, it will be demonstrated how some expressions are valid only for specific cases. The objective is to alert to the possibility that specific cases are being taught as if they were the only possible description of the complexity of physical reality and not as physical models with their respective limitations.
