## 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.

## Course contents

Mechanics program

Elements of vector algebra.

Kinematics.- Point particles and reference frames. Position, velocity and acceleration vectors. Rectilinear motions. Uniform circular motion. Simple and damped harmonic motion. Applications to kinematics of particle systems: the fundamental formula of the rigid  body kinematics. Angular velocity. Kinematics of relative motions: transfer of  displacements, velocity, acceleration within reference frames in relative motion.

Dynamics.- Different types of force. Static measurement of a force. General concepts of  statics and of friction phenomena. First and second law of dynamics. Inertial mass. 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.
