For 9th grade students - Physical Space

Physics in 9th grade is an important stage that completes the first cycle of studying this science and prepares students for further challenges. This year the emphasis is shifted to electrical, magnetic and optical phenomena, as well as to get acquainted with the basics of nuclear physics. It is here that students learn to see a holistic picture, summarizing the knowledge gained in previous classes, and building logicalConnections between different sections of physics.

If students have gaps in the understanding of mechanics, thermal phenomena or other topics, we offer effective assistance. Our lessons allow not only to master new topics, but also to systematize and fill educational losses. We will help you to confidently conquer this subject, realize its beauty and prepare for a new, even more exciting level of study.
