JUSTIFICATION:
The fundamental concepts of kinematics and dynamics and their generalization to three-dimensional space strongly contribute to a better understanding of the surrounding environment and the phenomena that condition and determine it.
OBJECTIVES:
This curricular unit aims teaching and developing the ability to solve problems related to the kinematics and kinetics of particles, systems of particles and rigid bodies, by introducing theoretical concepts and practical methodologies.
COMPETENCES AND LEARNING OUTCOMES:
Knowledge: Define and demonstrate knowledge in areas of basic science. Identify key concepts related to kinematics and dynamics of systems.
Comprehension: Interpret and identify the phenomena associated with movement of systems and the causes that produce nuclear knowledge in engineering. Interpret the phenomena in the light of empirical knowledge.
Application: Develop knowledge in fundamental sciences. Apply the concepts of kinematics and dynamics in the resolution of practical cases.
Analysis: Analyze the relationship between kinematics and systems dynamics. Understand the difference between particle and system of particles and the implications in the response.
The students are required to have basic knowledge on Mathematics and Physics acquired before entering at FEUP, complemented with the Mathematical Analysis and Algebra courses of the 1st year.

DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:
The fundamental concepts of kinematics and dynamics and its generalization to three-dimensional space contribute significantly to a better perception of the surrounding environment and phenomena that condition it.
All subjects of the course are discussed in the theoretical and practical classes. Exposition and explanation of concepts, principles and methods, complemented and illustrated with the resolution of some of the problems proposed at the exercises sheets, are done in the theoretical classes. In the practical classes it is promoted the discussion of the problems proposed at the exercises sheets, being the students asked to solve them individually or in group.
DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
Students are encouraged to apply the concepts of kinematics and dynamics in the resolution of practical cases, to analyze and relate kinematics and dynamics of systems, to understand the difference between particle and system of particles and the implications for the response.

Achieving a final classification requires the attendance of the Curricular Unit (CU), as established in the FEUP evaluation rules. A student is considered to have attended a CU if, after been regularly enrolled, he does not exceed the limit number of absences that corresponds to 25% of the expected number of face-to-face classes.
The final classification is defined through a distributed evaluation component (consisting of one test to be carried out during the class period and by the evaluation of the student's participation in the theoretical classes) and a final exam. The distributed evaluation is optional. All the evaluation components are expressed on a scale of 0 to 20 values.
The final classification is computed using the following formula:
CF = max {CT ; EF}
Where:
CT = PP x CPT + PA x CAD + PF x EF
With:
CPT - average classification of participation in theoretical classes by answering to online questionnaires during these classes: correct answer to 50% of the total of the questions asked in questionnaire "i" implies CPTi =20, otherwise, CPTi = 0;
CAD - classification of the evaluation test to be carried during the class period;
EF - classification of the final exam (ordinary and/or appeal seasons).
And PP, PA and PF the weights associated to the classifications CPT, CAD and EF:
PP = 0,10 (10%)
PA = 0,20 (20%)
PF = 0,70 (70%)
NOTE 1: The evaluations associated to CPT and CAD are optional. If a student does not participate in any of them, the corresponding weights are added to PF.
NOTE 2: The formulation is valid for all the students registered in this curricular unit.
NOTE 3: The classification of the distributed evaluation obtained in previous school years won’t be valid in the present school year.
NOTE 4: The final maximum grade that any student can obtain through the presented formula (CF) is 17. To obtain a grade of 18 or higher, the student must take an oral exam. Only students with a CF of 18 or higher are admitted to an oral exam.
Optionally, students can participate in the questionnaires to be carried out in the theoretical classes (CPT – See "Fórmula de cálculo da classificação final") that will constitute the component of the distributed evaluation of the curricular unit. This evaluation will be considered in the final classification only if it is obtained during the current school year.
See NOTE 2 of item "Fórmula de cálculo da classificação
final".
Tests to improve the classification of the distributed evaluation are not foreseen, but improving the classification of the final exam of the ordinary season is possible by perfomring the final exam of the appeal season.
Estimated working time outside classes: 3 hours/week.
