The chapter will conclude with a presentation of the more modern approach, using “Lagrangian Mechanics”, that is currently preferred in physics and forms the basis for extending our description of physics to the microscopic world (e.g. Figure 8.1: Three roller coasters that start at the same height and end at the same height.
