# Physics 1

FEKT-BKC-FY1Acad. year: 2023/2024

The course Physics 1 deals at first with basis of particle mechanics. Gained knowledge is used to study the influence of physical fields on particle motion. Significant part of the subject is focused on electric and magnetic fields, their formation, laws and mutual nature leading to the concept of electromagnetic field and Maxwell’s equations.

Exam:

Up to 65 pts.

Exam has written form, it consists of the test with selection questions, a theoretical part and examples. To pass the exam it is necessary to gain at least 6 points in theoretical part and in examples.

Attendance in seminars is compulsory. Excused seminars can be made up.

The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.

Aims

The aim of the course is to provide students with a clear and logical interpretation of the basic physical concepts and laws of mechanics, electricity and magnetism. To reinforce the understanding of these concepts and laws through a wide range of interesting applications.

The graduate of the course is able to:

- define the concepts of kinematics and particle dynamics, electric and magnetic fields using differential and integral calculus,

- describe the basic laws and principles in these areas,

- discuss the conditions for the application of the laws of mechanics, electricity and magnetism, explain the relationships between them and distinguish which form of laws is advantageous to apply in a given field,

- apply the laws studied in their interrelationships, classify the forces acting in electric and magnetic fields and calculate simple trajectories of charged particles in these fields,

- apply the laws studied in the physics laboratory,

- compare and analyse the laws of electric and magnetic fields. They can explain their common nature and explain why we talk about the electromagnetic field described by Maxwell's equations.
