Candidate of Physical and Mathematical Sciences, lecturer of the Department of Physics and Mathematics Kalzhanova G. held an open lecture session for students of the 3rd year of the educational program «Physics» in the discipline «Classical Mechanics». An open lecture session on classical mechanics was devoted to the topic of oscillatory motion. The purpose of the lecture was for students to learn how to solve second-order differential equations that arise when describing oscillatory movements. The teacher actively involved students in the discussion process, asking questions that directed them to independently comprehend the material.
