Main themes
The course is structured in two parts. The first addresses point mass mechanics, and the second electrostatics. The second part concludes with some elements introductory to the theory of electrical circuits. Both components of the course share a common conceptual framework, in which basic physics concepts are introduced in a unified approach (forces, potential and mechanical energies, conservation equations). The first part introduces the concepts of geometry and vector spaces necessary to express the notions of forces and torques, and in particular the conditions of static equilibrium. Next, the concepts and tools of kinematics are developed, leading to Newton's principles, their physical meaning and consequences. Finally, based on these principles, the conservation laws of linear momentum and energy are established, by also discussing their physical significance. The second part introduces the main quantities and laws relevant to electrostatics in vacuum, exploiting the physics concepts of the first part of the course. The generalisation of these laws to dielectric media is developed. Conducting materials are considered, leading to the concept of electrical resistance. Then follows an introduction to the basics of the theory of electrical circuits (Ohm's and Kirchhoff's laws, electrical capacitance and inductance).
Aims

Content
Part 1 : Point mass mechanics - geometry and vector spaces - forces - torques - static equilibrium - kinematics - Newton's principles - conservation laws ' collisions ' periodic motion
Part 2 : Electrostatics, basics of circuit theory - Electrostatics in vacuum - Electrostatics in matter - Ohm's and Kirchhoff's laws - Basics of electrical circuits
Teaching methods
The two parts (mechanics and electricity) share a common formalism and the concepts introduced in each part are treated in a unified manner (forces, potential functions, energy, conservation laws,').
In addition to formal lectures, tutored sessions are organized on a weekly basis (APE and APP), during which the students work in groups of 6 with a problem-based learning approach.
Every week, each student must complete a series of exercices within the MasteringPhysics learning environment.
Evaluation methods
Written individual exam covering both parts of the course. Details are defined on the course website.
