Prerequisites

It is assumed that the student (1) has a sufficient knowledge of French to enable him or her to follow or conduct a structured discussion without ambiguity, whether orally or in writing, (2) understands basic mathematical analysis tools such as linear algebra, geometry, trigonometry and differential and integral calculus, and (3) is familiar with graphics, including three-dimensional ones.

Main themes

 

·      Physical quantities and measurements.

·      Kinematics and dynamics of the particle (motion along a straight line and circular motion, relative motions, composition of motions, Newton¿s laws of motion, friction, gravitation, non-inertial frames of reference).

·      Conservation principles (work, kinetic energy, potential energy, relation between force and potential energy, conservation of mechanical energy, conservation of momentum).

·      Statics and dynamics of rigid bodies (rotational motion and moment of inertia, Huygens¿ theorem, torque, conservation of angular momentum, equilibrium).

·      Statics and dynamics of fluids (pressure in a fluid, law of hydrostatic equilibrium, Archimede¿s principle, surface phenomena, motion of a fluid and stream lines, Bernoulli¿s equation, viscosity).

    b.  Specific learning outcomes of the teaching unit

    At the end of this teaching unit, the student will be able to:

    • handle the basic mathematical analysis tools of physics;
    • understand the fundamental laws of classical mechanics;
    • convert a literal statement for classical mechanics into mathematical equations and vice versa;
    • represent the behaviour of a simple physical system using a mathematical model and assess the latter's validity;
    • apply physical theories to solve a simple problem of classical mechanics and identify relevant and non-relevant data;
    • argue in relation to the validity of a classical mechanics result;
    • carry out a simple classical mechanics experiment and analyse its results, in the light of the theoretical reference framework, taking into account different sources of possible errors;
    • explain and justify the choice of a method of measurement in physics and apply it to obtain a result;
    • transpose the theoretical concepts from classical mechanics to concrete problems related to biology, chemistry, geography, and veterinary medicine.

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.

Teaching methods

The teaching activities include (1) the theoretical course (14 sessions of 2 hours each), (2) an introductory session of 2 hours on the practical laboratory work (mandatory), (3) guided exercise sessions (16 sessions of 2 hours each), (4) a practical laboratory work (4 sessions of 2 hours each), (5) the ReflexSciences tests (see below) and (6) the tutorial. It is essential to have a simple scientific calculator for the supervised exercise sessions and the practical laboratory work.

The different subjects are presented in the theoretical course via slides and blackboard notes. The fundamental concepts are illustrated using applications from modern life, short films or animations, and experiments. The guided exercise sessions play an essential role in the comprehension of the theoretical course and allow the application of the studied theoretical concepts to real problems. The list of problems to be solved during an exercise session and a list of additional problems appears on the LPHY1121 MoodleUCL site approximately one week prior to the exercise session. Preparation of the problems to be solved is crucial. Participation in the practical laboratory sessions is mandatory. A description of the tasks to be carried out in the laboratory together with an introductory video appear on the LPHY1101 MoodleUCL site approximately one week prior to each session. It is essential that this description be read carefully, the video be watched and the preliminary questions be answered prior to the session. A laboratory report must be written and submitted at the end of the session. This report is assessed. Each week, a ReflexSciences test (short video and multiple-choice questions) is proposed on the LPHY1101 MoodleUCL site. The time to answer this test is limited. The purpose is to measure the (fine) understanding of the subjects studied the previous week. Each test is corrected during the guided exercise session that follows. A tutorial, during which the students may ask their questions to the teaching team, is held each week. The best approach is to work consistently throughout the semester. In particular, it is essential that students regularly solve the exercises themselves, and do not simply read the solutions.

 

Evaluation methods

Laboratory reports count for 20% of the final mark. The exam during the January session (and the other sessions) is written, lasts four hours and counts for 80% of the final mark. If the score obtained in the ReflexSciences tests (see below) is greater than or equal to 10/20 (14/20), a bonus point (two bonus points) is (are) awarded, provided that the mark obtained at the exam is greater or equal to 8.5/20.

The exam includes various problems similar to those solved in the guided exercise sessions (one of these problems is taken from the list of problems solved in the sessions) and some questions that aim to check that the concepts and developments presented during the theoretical course have well been mastered (comprehension questions, demonstrations, true or false with or without justification, multiple-choice questions or sentences to complete).

All the subjects addressed during the theoretical lessons and the guided exercise sessions must be known for the exam. However, the students have access to a form with the main formulas, which is posted on the LPHY1101 MoodleUCL site.

It is essential to bring a simple scientific calculator to the exam.

The modalities mentioned above are valid whatever the exam session.

Online resources

The slides and the short films or animations projected during the theoretical course, the list of exercises to be solved, the supports for practical laboratory work, exam examples and other useful documents are made available to students on the MoodleUCL website of LPHY1101.
