The mechanics presented here concern exclusively the mechanics of the point.
In practice, it concerns material objects whose spatial extension is very small: their deformations and the energy linked to their own rotational movement can therefore be neglected in comparison with the energies involved. However, an object as voluminous such as the earth or the sun can in some cases be assimilated to a point in terms of its action on bodies in its surroundings, for instance.

Le cours d'électricité et Magnétisme couvre les principes fondamentaux de l'électromagnétisme, abordant des sujets comme l'électrostatique, où l'on explore les charges, les forces entre elles, les champs et potentiels électriques, ainsi que les condensateurs et leur capacité à stocker l'énergie. Il examine également les conducteurs en équilibre électrostatique, notamment la distribution des charges et l'écrantage électrostatique. Le cours traite des courants continus, y compris la loi d'Ohm, les circuits électriques, et la puissance électrique. La magnétostatique est étudiée à travers le champ magnétique, les forces sur les charges en mouvement, et les courants.

This course will introduce you to various techniques used in chemistry laboratory as well as procedures and some methods of identification of chemical compounds.

The contents of this course material illustrate important concepts and principles in general chemistry. Three basic goals guided the development of all experiments in this material:

the experiments illustrate the concepts learned in the classroom; (2) the experiments are clearly and concisely written so that students will easily understand the task at hand, will work with minimal because the manual provides enough information on experimental procedures, and will be able to perform the experiments in 3 hour laboratory period; and (3) the experiments are not only simple demonstrations, but also contain a sense of discovery. In addition, laboratory safety tips as well as common laboratory techniques are explored. Practicals in  chemistry 1 consists of three units that : Unit I in the course introduce you to laboratory safety rules, common laboratory apparatus and a series of detailed instructions and explanations dealing with the basic laboratory techniques of chemistry. Unit II contains experiments that introduce you to the techniques used in the preparation of solutions. Unit III consist of experimental method for the determination values of the wavelength of the atoms by atomic spectra using a diffraction grating.
