- Use appropriate physical quantities to describe properties, states, interactions and events
- Formulate physics'''' problems in mathematical language applied to physical quantities
- Recognize the usefulness of mathematical tools and models in solving physics'''' problems
- Analyze and solve problems in the context of mechanics and biomechanics (translation and rotation of bodies)
- Associate movements under the action of forces to transferences of energy
- Describe using mathematical tools oscillatory and wave phenomena.

Teaching method

The course is organized in lectures where the theory is presented, problem-solving sessions where problems are discussed with the instructor, and laboratory sessions.

Evaluation method

Assessment

The assessment has 2 components: laboratory and theoretical-practical.

 

Laboratory component

Exclusively for non-attending students.

Carrying out all the laboratory practicals is mandatory.

Each practical assignment leads to a grade based on the report submitted.

The grade for the laboratory component, NLab, is the average of the grades for the practical work with protocol and the grade for the report on the work without protocol.

 

Attendance

A student obtains attendance if he/she has completed all practical work and achieved a minimum grade of 10 in the laboratory component.

 

Theoretical-practical component

Consists of 2 tests or a retake exam.

A student passes this component if the score on the tests or the retake exam, NTE, is equal to or greater than 10 points.

 

Tests

Two theoretical-practical tests are carried out during the period stipulated in the school calendar.

Each test consists of 10 multiple-choice or short-answer questions (6 points) and one or more problems (4 points). The final grade for the tests is the sum of the grades obtained in the 2 tests.

In multiple choice questions, wrong answers other than the first one are discounted by 1/(n-1) where n is the number of answer options.

Students may carry with them during testing a self-written form on an A4 page. This form can only contain equations and constants with their respective descriptions.

 

Exam

Only students who have obtained attendance are admitted to the retake exam.

The retake exam consists of 20 multiple-choice or short-answer questions (12 points) and 2 or more problems (8 points).

In multiple choice questions, wrong answers other than the first two are discounted by 1/(n-1) where n is the number of answer options.

Students may carry with them during the exam a self-written form on an A4 sheet of paper. This form can only contain equations and constants with their respective descriptions.

 

Final grade

1. For students without attendance or with attendance obtained in 2023/24: 30% NLab + 70% NTE

2. For students with attendance obtained until 2022/23: 100% NTE.

 

Grade improvement

It is possible to improve the grade of the theoretical-practical component. In case of improvement, the new final grade is calculated according to the rule presented in the previous item.

It is not possible to make improvements to the laboratory component.
