Objectives

At the end of this module, the student will have understood and be able to explain (main concepts):

 

Optics :

Gauss approximation, nature of objects and images, properties of single optical elements (dioptres, mirrors, lenses) and optical instruments made up of several single elements.

 

Mechanics :

Kinematics of a material point, the three Newton laws of dynamic, the theorem of kinetic energy, the concepts of relativity and inertial forces.

 

The student will be able to:

 

Optics :

Manipulate optical elements to constitute an optical instrument. Realize geometric constructions of images through several optical elements. Use formula to calculate the size and positions of images.

 

Mechanics :

Describe the movement (position, speed, acceleration) of a material point in different coordinate systems based on a given reference frame. Determine the external forces experienced by a material point and know the expression of the usual mechanical forces (gravity, electromagnetic, restoring force of a spring, reaction of a support and strength of friction, inertial pseudo-forces). Determine the trajectory or timetables equations of a material point from the fundamental principle of dynamics, the theorem of angular momentum and / or kinetic energy theorem.

Needed prerequisite

-Notation for differentiation.

- trigonometry

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
