### Course Objectives

The goal of the course is to provide the students with knowledge of basic principles of the mechanics with particular regard to the concepts of force, energy and wave propagation; and with the ability (through classroom excercises and homeworks) to schematize a natural phenomenon, to apply the proper physical laws, and to critically evaluate the results.

### Course Content

- Kinematics of a point particle: motion in one and more dimensions, relative motions, vectorial composition of velocities.
- Dynamics of a point particle: Newton’s laws, concept of force, weight force, constraint reaction forces, sliding friction, viscous friction, elastic force, harmonic motion, the simple pendulum, inertial and non-inertial frames of reference, fictitious forces.
- Work, energy, momentum: definition of work, theorem of kinetic energy, work of the weight, work of the elastic force, conservative forces, potential energy, mechanical energy, momentum and impulse, torque, angular momentum.
- Dynamics of a system of particles: external and internal forces, momentum of the system, first cardinal equation of the dynamics, isolated system and conservation of momentum, motion of the center of mass, collisions.
- Gravitation: Kepler’s laws, law of universal gravitation, Cavendish experiment, gravitational potential energy, gravitational field, motion of a satellite in circular orbit, escape velocity.
- Waves in elastic media: longitudinal and transverse waves, mathematical description of wave propagation, harmonic waves, D'Alembert equation, vibrating string, elastic waves in a bar and in a gas, interference, beats, standing waves, Doppler effect.

### Learning Outcomes (Dublin Descriptors)

On successful completion of this course, the student should

- have acquired a good knowledge and understanding of the fundamental concepts in Physics and a method of logical and rigorous approach to a physical problem.
- be able to schematize a natural phenomenon and to apply correctly basic physical laws to solve simple problems in mechanics.
- be able to choose the proper model to describe a physical phenomenon and be aware of the degree of approximation adopted.
- be able to communicate in a simple but rigorous way the acquired knowledge in Physics to other colleagues as well as to non-experts.
