Learning outcomes

To assimilate basic concepts of General Physics (with special regard to Particle Mechanics, to the Principles of Thermodynamics and to the laws of Electromagnetism in Vacuum) 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.

Impulse and linear momentum. Newton's law on gravitation. The main problem of dynamics. The third law of dynamics. Applications to dynamics of particle systems. Linear and angular momentum conservation. Collision problems. The cardinal equations of dynamics. Center of mass and its properties. Moments of inertia. The Huygens – Steiner's theorem. Rotational inertia.

Work and energy.-Work of one force and of a system of forces. The work-energy theorem. The Koenig's  theorem. Properties of kinetic energy. Positional and conservative forces. Conditions to be fulfilled for a force field to be conservative. Potentials and potential energies. Conservation of mechanical energy. Different types of equilibrium.
