I have learned the basic knowledge of linear motion, displacement calculation and kinematic basics in this course. The concept of negative displacement is totally new for me. I like the clear and easy-to-understand knowledge explanation of this course. There are not many obvious weak points. It can be improved by adding more practical examples and exercise questions. I hope to learn basic physics knowledge in a simple way, so I choose this beginner-friendly course.
