30780 - General Physics T

Learning outcomes

To assimilate basic concepts of General Physics (with special regard to Newtonian Mechanics and to the Principles of Thermodynamics) and their treatment by means of mathematical analysis, vector algebra and integral calculus. To acquire the scientific-technical methodology which is necessary for quantitative problem-solving in physics.
