Física I

The course unit consists of three types of classes:
1. Theoretical classes, in which the syllabus content is presented.
2. Theoretical-practical classes, in which practical exercises are solved, applying the knowledge presented in the theoretical classes.
3. Laboratory classes, in which experiments are carried out within the scope of the course unit’s syllabus.

The methodologies listed are consistent with the pedagogical model adopted for the course unit and aligned with its objectives.

The Physics Course Unit (CU) aims to provide students with the basic knowledge of Physics in the field of Classical Mechanics, relevant to engineering in general and fundamental for a proper understanding of many practical engineering solutions. It also aims to provide the knowledge and tools essential for understanding subjects such as Solid Mechanics, taught in other CUs.

Given that this is an introductory CU in Physics at higher-education level, the teaching methodology must focus on consolidating the theoretical concepts and principles of Physics. This is suited to lecture-based teaching of the theory, complemented where necessary by solving exercises that illustrate practical situations, and by practical laboratory work.

1. Vector calculus: scalar and vector quantities; types of vectors; graphical operations with free vectors; vector projection; unit vectors and direction cosines; analytical operations with vectors.
2. Kinematics of a particle: frames of reference; position, velocity and acceleration vectors; one-dimensional motion; circular motion; projectile motion; three-dimensional motion.
3. Dynamics of a particle and of a rigid body: linear momentum and its conservation; Newton’s laws; impulse; applied, constraint and friction forces; angular momentum; moment of a force (torque); moment of inertia; rotation of a rigid body; conservation of angular momentum.
4. Work and energy: work; power; kinetic energy (particle and rigid body); work-energy theorem; conservative forces and potential energy; collisions.
5. Statics of a particle and of a rigid body: equilibrium of the particle and of the rigid body; supports; analysis of the equilibrium of structures.
