# Physics 1

FEKT-BPC-FY1AAcad. year: 2020/2021

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.
