Subject description
MECHANICS
First, we give the physical foundations of kinematics, then in the context of dynamics we discuss Newton's laws, then the theorem on kinetic and gravitational potential energy, and finally the theorem on angular momentum and its conservation. As a special example, we then first derive the harmonic undamped oscillation equations for different types of mechanical pendulums. In the following we continue with a more demanding theoretical treatment of damped, forced and coupled harmonic oscillation. We also briefly describe different ways of deformation of solid and liquid substances and the corresponding expressions for deformation energies. Then we move on to a physical description of the basic properties of liquids and a simplified description of the movement of liquids using the Bernoulli equation. As an example of using Bernoulli's equation, we calculate the drag forces acting on bodies in a fluid at high speeds. We continue with the derivation of Poiseuille – Hagen equation for viscous fluid flow through thin pipes. In the context of the treatment of surface tension, we derive Laplace's and Young's equations and consider capillary rise and adhesion of liquid droplets to solid surfaces. At the end, we also give the theoretical foundations of the physical description of mechanical wave.
THERMODYNAMICS
We begin with an explanation of the 1st law of thermodynamics and a presentation of the kinetic theory of gases, where we define also various thermodynamic functions, equations of state of matter such as the ideal gas equation and describe possible phase transitions between different phases of matter. We also present the equations describing heat transfer through thermal conductors. We continue with the law of entropy and the calculation of the efficiencies of heat and cooling machines. At the end, we process the physical description of the thermal expansion of solids and liquids.
All theoretical considerations in mechanics and thermodynamics are illustrated with relevant experiments, which are shown in the lectures.
