Topic outline

This page compiles a series of lectures and Tutorials on the mechanics of a material point. It is intended for firstyear computer science students in the LMD system and can serve as a support for a course taught to students.
The mechanics of a material point is a foundational topic in classical physics, focusing on the behavior of objects when treated as point masses—entities with mass but no physical dimensions. This simplification allows for the exploration of fundamental principles governing motion and force in a clear and precise manner. In Physics 1, the study of these principles forms the basis for understanding more complex physical systems.
This course begins with an examination of kinematics, where the motion of a material point is described without considering the forces that cause it. Following this, the focus shifts to dynamics, which introduces the forces responsible for changes in motion, providing a deeper understanding of how and why objects move. The final component addresses work and energy, exploring the relationships between forces and the energy transformations that occur during motion. Together, these topics provide a comprehensive introduction to the mechanics of a material point, establishing the essential groundwork for further study in physics and related disciplines.

Forum Response: Any courserelated questions should be posted on the dedicated forum so that everyone can benefit from my response. I commit to answering questions posted within 72 hours.
Email: I commit to responding to emails within 72 hours of receiving them, except in unforeseen circumstances. Please note that the preferred communication channel is the forum; email is reserved for "urgent" matters (e.g., issues accessing the platform) and should be used judiciously.


At the end of this course, the student will have acquired scientific skills related to:
Understanding the assumptions of classical mechanics,
Isolating an object assimilable to a material point,
Describing and writing the motion of a material point in different coordinate systems,
Understanding and being able to calculate the velocities and accelerations of a mobile for any trajectory,
Describing, writing, and analyzing external actions exerted on a material point,
Understanding, writing, and solving the equations of dynamics governing the motion of a material point.
The calculation of work and energy in simple situations;
The application of conservation principles in mechanics.

The final evaluation consists of:
 A final exam, covering everything you have learned in the course during the semester, which counts for 60% of the final grade.
 Continuous and regular assessment, accounting for the remaining 40%, allows you to earn points throughout the semester.
 The average of written test scores,
 Grades obtained in individual and group work,
 The average score of TD (directed work) assessments.
