Raffaello BIANCO


Provide the student with the fundamentals of general physics, including kinematics, statics and dynamics of material points and rigid bodies, oscillations, celestial mechanics, fluid mechanics, and acoustics. The conceptual and formal foundations will be discussed along with the aspects of practical understanding functional to solving problems and carrying out exercises.

Admission requirements

- element of algebra, trigonometry, analysis

Course contents

9 CFU, 36 lessons, each lasting 2 hours, for a total of 72 hours of classroom teaching.

CELESTIAL MECHANICS - Universal gravitational force and gravitational mass. Gravitational field generated by a homogeneous spherical object and the relationship between gravitational force and weight force. Kepler's laws. Motion of satellites. Escape velocity.

RIGID BODY - Definition of a rigid body. Degrees of freedom. Description of a continuous body. Kinematics of a rigid body, instantaneous axis of rotation. Rotational motion around a fixed axis: Moment of inertia, Huygens-Steiner theorem (NO DIM) and connection with Koenig's theorem, Kinetic energy, Axial and orthogonal component of momentum and moment of force. Axial cardinal equation. Physical pendulum (i.e. compound pendulum).

Teaching methods

lectures on the blackboard, discussion of conceptual and formal aspects and problems, guided resolution of exercises also through an additional 20 hours of tutoring with a PhD student. strongly recommended attendance (not compulsory) language of the course: Italian

Assessment methods

The exam consists of a written test lasting 3 hours on the topics defined in the "Course Contents" section. The test includes open-ended questions and exercises to solve and aims to assess both the theoretical knowledge/understanding of the topics and the ability to apply the learned concepts to solve practical problems. The final grade is expressed on a scale of thirty and passing the exam requires a final evaluation >= 18/30. For those who obtain a grade >= 18 on the written test, it is also possible to take an oral exam as a completion, which allows for the possibility of adjusting the written grade by -4/+4 points.

Learning outcomes

Knowledge and Understanding: acquire the knowledge and understanding of classical mechanics and of the more fundamental aspects of fluid dynamics and thermodynamics, through the effective use of university textbooks.

Ability to apply Knowledge and understanding: independently solve exercises, design and describe feasible experiments to measure various physical quantities

Making Judgements: acquire the data necessary to solve a given problem, evaluate the feasibility of experiments, generalize and apply what has been learned in class to problems not explicitly covered

Communication skills: interacting with teachers in professional language, communicating the acquired knowledge in written format, with particular attention to mathematical formalism and dimensional analysis

Learning skills: acquire those skills and knowledge necessary to continue studies with more advanced physics courses, e.g. analytical mechanics, statistical mechanics, etc.
