This is a classic mechanics course for students in the Math/Physics preparatory classes. However, thanks to the supplements in this course, the future teacher will also be able to find subjects to think about and go into in greater depth. This course covers the main aspects of Newtonian mechanics, such as the notion of force, Newton's laws, the energy point of view, angular momentum and the forces of inertia. It's a natural presentation that tries not to be too abstract, like that of torsors or analytical mechanics. More technical aspects may be covered in supplements.
