Learning outcomes

This course aims to give the students the knowledge of the classical mechanics' basic concepts and how they can be expressed in mathematical form. It is the basic information for a future engeneer and a base requirement for the more specialistics courses. The students have to reach a knowledge of the scientific methods and of the natural laws so that they can solve problems connected mainly to the point mechanics and to the dynamical systems.

Course contents

Vector calculus

Scalar and vector calculus. Geometrical definition of a vector. Sum and difference between vectors. Product of a scalar and a vector. Scalar and vector product. Vectors in a cartesian notation. Vector operations in a cartesian notation.

Kinematics

Mass point, position and motion, reference frame systems. Units of measurement of space and time. Dimensions of a physical quantity. System of measurement units: MKS and CGS. Motion description and vector equation of motion. Trajectory equation and time law. Intrinsic description of motion. Speed, velocity, acceleration: definition and units of measurements. Examples of base motion types. Change of reference systems.

Point dynamics

Definition of force, dynamometer and unit of measurement. Vector nature of forces. Constraints, reactions, friction and frictionless constraints. Equilibrium conditions. First principle of dynamics: Galileo's experiments and inertial reference frames. Second principle of dynamics. Fundamental interactions; weight force, gravitational force, elastic force, static friction force and kinematic friction force. Motion of a point along a line. Simple pendulus. Real forces and pseudoforces.

Work and Energy

Point system dynamics

Isolated systems: internal and external forces. Momentum. Third principle of dynamics: action and reaction principle. Impulse and impulsive forces. Elastic and anelastic collisions. Simple collision problems. Total forces and force moments in a system. Angular moment. Center of mass of a system of points and center-of-mass theorems. Cardinal equations.

Teaching methods

Public lessons for the theory and typical exercises.

Assessment methods

The assessment of the knowledge on classical mechanics is achived throu a written and an oral examination. In the written examination, the student will have to solve one or more exercises on mechanics and will have to answer properly on selected items of the course. The written examination can be substituted by 2 or 3 written tests on parts of the program that will be performed during the lesson periods. In the oral examination, the student will have to show his/her knowledge on the notions of mechanics and will have to describe quantitatively the natural phenomena encountered in the course.
