The Physics 1 course deals with the fundamental laws of mechanics and hydromechanics, essential for understanding any scientific and technological application the student will deal with during his training.
Scientific method, experimental uncertainties, dimensional analysis and units of measurement. Reference systems and vector, differential and integral calculation elements. Kinematics of the material point: position, displacement, velocity, acceleration. Radial and tangential acceleration. Uniformly accelerated motion, circular motion, harmonic motion. Principles of the dynamics of the material point: forces, inertial systems, non-inertial and apparent forces (brief remarks); force weight, friction forces; elastic forces, gravitational force (brief remark) Work of a force, kinetic energy and power; conservative forces and potential energy. Impulse and momentum; angular momentum and momentum of a force; System of material points laws of conservation of momentum and angular momentum; center of mass and its motion; applications with elastic and inelastic collisions. Rigid body: rotation around a fixed axis; moment of inertia; rolling motion.
Attendance and active participation in the proposed educational activities (lectures and exercises) and individual study will allow the student to:
- acquire the ability to describe and analyze the basic concepts concerning measurement of physical quantities
- understand and apply the fundamental laws of Kinematics
- understand and apply the fundamental laws of Dynamics to a variety of common situations
- understand, describe and apply the basic concepts of Kinetic and Potential Energy, Work and Power
- extend the fundamental laws of Kinetics and Dynamics to Rotation
- understand and apply the concepts of Equilibrium and Elasticity
- acquire the ability to describe and analyze the basic concepts regarding Fluid Satics and Dynamics
- understand Harmonic Motion and its applications
The student will be encouraged to understand the advantages and limitations connected to the use of schematics and models, employ scientific language and formalism correctly, recognize the applicability of schematizations and models in real-life situations, set and solve exercises and problems within the proposed contents and critically evaluate the results.
Teaching is divided into lectures conducted by the teacher in which the theory will be exposed, which will be applied to different examples and through the resolution of exercises. In his personal work the student will have to acquire the knowledge and concepts underlying mechanics and hydromechanics and be able to solve exercises.
