Course contents


Students participating in this course have a basic knowlege background in mathematics. They know about simple equations and cartesian geometry, basic geometrical shapes in 2D and 3D. The first lecture deals briefly with a review of this basic requirements.

Basic elements of mathematical analysis

Power laws. Logarithms. Equations. Reference systems. Geometric angles. Functions. Geometry.


What is physics? The experimental method and physical quantities and laws. Measurment and uncertainty. Measurement units. Dimensional analysis.

Kinematics in one direction

Reference systems. Displacement. Scalar mean velocity. Vector velocity. One dimensional straight movement. Acceleration. Accelerated movement. Falling objects.


Definition of a vector. Components of a vector. Sum, difference and scalar and vector product. 


Newton's laws. Force. Mass and Newton's second law. Force diagrams. Gravitation.

Circular movement

Work and energy.

Work with a constant force and with a variable force. Teorem of the kinetic energy. Potential energy and gravitation. Elastic potential energy. Conservative and non-conservative forces. Conservation of energy. Dissipative forces. Power.


Normal force. Frictional force. Inclined plane. Elasticity and Hooke's law. 

Elements of Statics of Rigid and Deformable Bodies

Moment of a Force. Levers. Efforts.

Electrical Phenomena: Electrostatics

 Static electricity. Electric charge, insulators and conductors, charge induction. Coulomb's law. Electric field, its field lines. Electric potential.

Electrical Phenomena: Electric Current

 Capacitors. Electric cells and batteries. Electric current. Electrical circuit. Ohm's first law. Ohm's second law. Power dissipated in the conductor. Continuous current circuits. Series resistors. Resistors in parallel. Notes on electrical risk.


 Elastic Waves. Electromagnetic waves



The teacher makes the material used in class for the theoretical part and for the exercises available online.

Fundamental will be the use of a reference text, among others available in university libraries:

Giancoli D., "Physics with Modern Physics", Ambrosiana Publishing House

Teaching methods

Applied physics. The course is based on lectures accompanied by exercises for applying the concepts presented. The material will be made available on IOL Unibo.

Assessment methods

The assessment jointly takes into account the level of knowledge and skills acquired by the student in relation to all the contents illustrated above. In particular, the knowledge and skills imparted by the Applied Physics module are assessed through a written exam lasting an hour and a half without the aid of notes or books in the presence of the teacher; the knowledge and skills imparted by the Technical Physics module are assessed through a written test containing three open-ended questions. 60 minutes are allocated for the technical physics test. During the course, it is not possible to use notes, handouts, books or other bibliographic material.

The final mark of the Principles of Physics course is given by the arithmetic average of the marks obtained in the Applied Physics and Technical Physics tests

Teaching tools

PC, video projector, slides with theory and exercises carried out in the classroom.
