Objectives

This course aims to present the concepts and the basic principles of Classic Mechanics, and relativity, with emphasis on  understanding and application in the analysis of  real world situations . Students should have the ability to manipulate fundamental concepts and knowi how to apply them to solve problems. Students will be motivated to consider the principles of Mechanics in other areas of knowledge and in technology.

Learning outcomes and competences

 Students should demonstrate good understanding of fundamental mechanical concepts (description of motion, mass, force, linear and angular momentum, energy) and relativity (relativity of space and time, space-time diagrams  and relativistic momentum and energy) by correctly solving problems of direct application of these concepts, and by  modeling and analysing, in terms of mechanics concepts, real world situations.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Distributed evaluation with final exam

Assessment Components

designation	Weight (%)
Defesa pública de dissertação, de relatório de projeto ou estágio, ou de tese	10,00
Exame	75,00
Teste	15,00
Total:	100,00

Eligibility for exams

Compulsory presence in 75% of the exercise and computing classes.

Calculation formula of final grade

PC: % grade of computational project

MT: % grade of tests

EX: % grade in Final exam

NF: Final grade (0,20)


NF =18 * Max [EX, (5*Ex+1*MT)/6]+ 2*PC

Classification improvement

General  Faculty of Science rules for exam component only.

Observations

The assessment of practical computing is done by filing a report from a group of 5 students at most,  on a set of assigned questions ( date to be set)

Students who wish to dispense with the presence in the TP must be registered in the TURMA de DISPENSA.  They can still do the mini-tests.
