No prerequisits are needed but following recommendations may be useful.
It is very important to have a deep knowledge of basic concepts of Mechanics and Relativity from first year.
It is important to master basic tools of differential and integral calculus (one variable), approximations with taylor series and to know elementary integrals.
It is also recommended to know basic principles of calculus in several variables for Analytical Mechanics and matrix diagonalisation for coupled oscillators and inertia tensor.
General goals are :
1. Learning more advanced subjects in Newtonian Mechanics;
2. Being able to deal with approximations, mainly by means of Taylor series.
3. Knowing and applying basic concepts of Analytical Mechanics.and recognize its importance for the whole of Physics.
Specific goals are :
. Resolving central forces problems using rotational symmetry.
. Dealing with particle systems and coupled oscillators.
. Studying rigid body rotations, inertia tensor and Euler equations.
. In Relativistic Dynamics, a deeper knowledge of relativistic linear momentum and energy and its applications.
. Knowing Lagragian and Hamiltonian formalisms.

It has been decided in principle by Facultat de Ciències and Coordinació del Grau de Física that teaching will be semipresential in first semester and presential in second semester. If allowed by sanitary situation, the start of presential teaching will be advanced.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

The qualification is 50% each semester. The semester qualification is equal parts for the two partials. Problem delivery can be 10% of qualification only in case of improvement.
The evaluation is successful if the student has attended all four partials, if the qualification is at least 5 and each semester at least 3.
If not successful or if successful but willing to improve students can do the final recovery examination. This final examination has two parts, one for each semester and the qualification of each part replaces the previous semester qualification only in case of improvement. The student can do both parts or only one. The qualifications of the final examination do not take in account problem delivery.
A student is evaluated if he/she has attended at least 35% of the qualification.
Students will be previously informed if a self-made formular is authorized in the examinations.
