**Course Enrolment Limitations**- The course is also offered to the students of the fields other than those the course is directly associated with.
**fields of study / plans the course is directly associated with**- Physics (programme PřF, M-FY)

**Course objectives**- The aim of the course is (1) to be able to describe with good understanding the general principles (1a) of the methodology of building up the concepts and (1b) of goings and procedures leading in formulation of the laws; (2) to apply them on the structure of newtonian mechanics and optionally on other theories.

Historical notes and actual remarks are organic parts of the course. **Syllabus**- 1. The world of material objects. The psychical world. The real immaterial world.
- 2. Building of concepts in physics and creation of concepts in mathematics. Empiricism. Experiment. Formal operation.
- 3. Interaction. Mass. Celerity–acceleration, momentum–acmomentation. Quantitative characteristic of the interaction. Force.
- 4. Equivalence of the laws. Zero acmomentation, conservation of momentum, Newton's third law of the motion.
- 5. Building-up a theory. From the interaction and Newton's third and second laws to the theorems about momentum and angular momentum. Conservation of momentum and of angular momentum. Newton's mechanics and newtonian mechanics.
- 6. Energy. From the second axiom to the conservation of mechanical energy of two-particle systems. Thomson's definition of energy. Energy-conservation principle.
- 7. Regularities. Definition. Natural reality. Rule. Law. Principle. Axiom. Synonymics and homonymics of physical terms. Statement, hypothesis, proposition, thesis, theorem, corollary.
- 8. Newton's axiomatics of mechanics. Reduction of six laws of motion to three axioms and commentaries to them. (Definitiones I-XII. Axiomata, sive Leges Motus. Colorraria I-V.)
- 9. Translation-rotation content of Newton's formulation of his first axiom. The problem of redundancy of the first axiom. Period dependent rightfulness of Newton's axiomatics. Structure of Newton's mechanics.
- 10. Einstein's deduction of the relationship energy–mass (1905).
- 11. Physical entities. Material objects, radiation. Field. Matter. Annihilation of particles. Materialization of radiation.
- 12. Equivalence principles. Gravitational mass–inertial mass, gravitational field–acceleration of the coordinate system, energy–mass, mass–volume.
- LITERATURE
- During the classes the student obtains printed aids: (1) Facsimilia of selected pages from uneasily accessible literature. (2) Czech translation of the facsimilia if they are not in English. (3) Sheets to special topics.
