good
Learn alot and I like it
Прекрасный курс, решение задач помогает разбираться в физике :)
Perpetual motion, in the sense of a system that operates indefinitely without an external energy source, is considered impossible according to the laws of physics, particularly the principles of thermodynamics. These laws state that energy cannot be created or destroyed, only transformed, and that any system loses energy through heat or friction, making perpetual motion unachievable.

I have learned a lot of knowledge about physics, which is also helpful for my general knowledge in life, but I still have some knowledge that I do not remember well. If I have the chance, I will study this physics course more deeply. The teacher is very good and the course is great.
1 Learned electrical mechanics and kinematics, etc 2 Electrical science 3 No weak points 4 Want to learn more
