These few lessons in Newtonian mechanics are part of a basic training course in Newtonian mechanics presented in the form of 5 MOOCs:
1) Newtonian mechanics
2) Mechanics of the material point
3) Mechanics: Change of Reference Frame and Relativity
4) Mechanics: Undeformable solid
5) Lagrangian mechanics (automatic translation)
To illustrate the concepts introduced in Part 1, we deal here with problems for which the mechanical system can be considered as a material point. In particular, this part covers problems to be treated in cylindrical or spherical coordinates, the problem of planetary orbits and accelerated reference frames. (automatic translation)
