Presentation

Course designed to deepen knowledge of Classical Mechanics to a level compatible with careers in science or technology fields where Physics and Mathematics have a strong presence. Problem solving and experimental work complement the theoretical skills.

Sustainable Development Goals

Learning Goals

Consolidate the fundamental concepts and laws of Classical Mechanics and extrapolate these concepts to interpretates common manifestations from the physical world.
Stimulate communication proficiencies that involves the ability to think in physical terms.
Develop skills to analyze, equate and solves problems that involve understanding the concepts and laws studied, applying appropriate mathematical algorithms.
Develop attitudes of responsibility and autonomy in the knowledge construction.
Introduce and apply the fundamental methods and techniques that involve experimental work, in terms of measurement, data processing, interpretation of results and presentation.
Develop simple experimental projects, from conception to execution, including analysis and processing of data and the discussion of results.

Contents

Component T and TP:
• Fundamentals of Newtonian Mechanics.
• Kinematics
• Particle dynamics
• Dynamics of a System of Particles.
• Conservation Principles
• Oscillatory Movement
• Relativistic kinematics
• Gravitational attraction and movement under the action of a Central Force
• Dynamics in Non-Inertial reference frames

PL component – experimental study of a set of topics such as:
• Movements in nature such as the projectile, exploring the effect of air resistance. The recordings of the positions and times are made with a video camera and/or motion sensors connected to electronic stopwatches;
• Newton's 2nd law study with simple mechanical systems
• Principles of conservation of energy, linear momentum, angular momentum using low friction systems (air track and rotational dynamics device) or ballistic pendulum;
• Study of oscillations (pendulum, springs and forced oscillations).
• Determination of the universal gravitation constant with a Cavendish balance
• Gyroscope precession

Teaching Methods

The conceptual and application component are articulated through concrete problems posed to the student to solve autonomously and in the end to share. In the lectures, are presented the contents of the syllabus and proposed some applications of such content; problem-solving classes, which are in conjunction with lectures, Will be proposed a series of problems to resolved; In laboratory classes, the student develop practical skills through experiments that favor the understanding of the theory and involve the manipulation of the variety of mechanical devices and sensors available (air chutes, rotation dynamics systems, position sensors, acceleration sensors and force coupled to chronometers, Cavendish balance, gyroscopes, stroboscopy).
Work guides are provided.
The theoretical evaluation (70%) may be taken or by performing two tests or by a final exam. The practical assessment (30%) relates to the proposed laboratory modules. Final grade= 070*T+0.30*PL
