**Prerequisites**- Completion of the subject F1030 Mechanics and molecular physics or corresponding knowledge.
**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) good understanding of the methodology of building up physical concepts, (2) to apply it to the concepts of newtonian mechanics, (3) deduction of its laws from the Axioms.

Much attention is paid to thinkable misconceptions and to possible misinterpretations of Newton's laws.

Historical notes and actual remarks are organic parts of the course. **Syllabus**- 1. Examples of (1) uncorrectly using terms, (2) misconceptions, (3) various misinterpretations of relations and laws: Newton's laws – Force – Free fall – The first law of thermodynamics.
- 2. Interaction laws. Galileo, Hooke, Newton, Coulomb, Archimedes. Stokes, Lorenz. Superposition principle.
- 3. Building up the concept 'force'. The second axiom. Definition vs. Natural law.
- 4. Mass. Primary concepts. Defined concepts. Building up the concepts 'inertial mass', 'gravitational mass', their otherness and their equivalence.
- 5. Time integration and trajectory integration of the second axiom. Change of linear momentum. Impuls of a net force. Change of kinetic energy. The work of the force. Two-particle systems. Additivity of kinetic energy. Configuration characteristic of the system. Potencial energy of the system. Additivity of potential energies.
- 6. The law of conservation of mechanical energy. Principle of conservation of energy.
- 7. Transformation of static and kinetic state characteristics. Coordinate systems. Inertial system. Basic configuration of the system. 'Arbitrality' of values of kinetic and potential energy.
- 8. Physical equivalence of gravitational field and accelerated coordination system. 'Fictiv' forces.
- 9. Multiparticle system. System and its sourroundings. Internal and external interactions. Center of mass. Mass center. Linear momentum, angular momentum, innate angular momentum. Kinetic energy. Innate kinetic energy. Virial.
- 10. Theorems about linear momentum and angular momentum. Conservation laws of linear momentum and angular momentum.
- 11. Structure of newtonian mechanics.
- 12. Einstein's deduction of the relationship energy–mass (1905).
- LITERATURE
- The needed background is given in student's acquaintance with any secondary school and university physics textbook used by him/her.
- 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 in Latin or in German. (3) Sheets to special topics.
