 Contents
 The course aims to help physics students learn the fundamental of classical physics and develop the calculation skills needed to apply these principles to real cases.
Topics include: linear and rotational motion, Newton’s laws, conservation of energy and momentum, gravitation, fluids, oscillations, and harmonic oscillator, both free, dumped and forced; basics of thermodynamics and the microscopic understanding of it based on elementary statistical mechanics; electrodynamics, the theory of electricity and magnetism. The course covers electrostatics (the electric field, electric potential, conductors), magnetostatics (electric currents vector potential), electromagnetic induction and an introduction to Maxwell’s equations (including wave solutions).
