16726 - General Physics A

Academic Year 2017/2018

Learning outcomes

This course aims to give the students the knowledge of the basic concepts of scientific method, in particular the fundamental physics concepts derived from Classical Mechanics. The students have to reach knowledge of the scientific methods and of the natural laws so that they can solve simple problems in a quantitative form.

Course contents

- Introduction and vectors: Units. Physical quantities. Vectors and vector algebra.

- Kinematics and dynamics: Motion along a straight line. Motion in two or three dimensions. Characteristics of force. Fundamental forces. Newton’s laws of motion.
- Work and energy: Work. Kinetic energy. Conservative forces. Potential energy and energy conservation. Non conservative forces.

- Momentum and collisions: Momentum and impulse. Collisions.
- Rotational motion: Rotation of rigid bodies. Kinematics of rotational motion. Moment of inertia. Rotational enenergy. Torque. Angular momentum. Conservation of angular momentum. Rigid body rotation about a fixed axis. Rolling without slipping.
- Fluid Mechanics: Density and pressure. Pressure, depth and Stevino’s law. Archimede’s principle. Fluid dynamics: continuity equation, Bernoulli’s equation.

- Periodic motion: Simple harmonic motion: equations and period.
- Gravitation: Newton’s law of gravitation.

Teaching methods

Class lectures supported by PC slides. Exercises and problems sessions. Tutorial activity is foreseen.

Assessment methods

Written examination to be passed before the (compulsory) oral examination.The oral examination must be passed within 6 months from the passed written one. If needed, more trials may be done within this period.The written exam consists in few problems and it typically lasts 90minutes. During the written exam the usage of a calculator and a formulary (provided by the professor) is allowed. The mark obtained following this examinations will be combined with the one of the General Physics A part to give the final mark for the General Physics course.
