Welcome to College Physics class!
Why Physics; How it works:
Physics is the branch of science that deals with the study of matter, energy, and the fundamental interactions between them.
1.Physics is hidden in every corner of life. Discovering it leads to a greater understanding of the universe, and physics is actually quite interesting.
2.Using physics thinking makes one live more wisely, and physics is not that difficult after all.
3.Mathematics follows physics like a shadow, and finding the connection between the two helps to clarify the story that physics tells.
4.Physics without experimental support is imperfect. Conducting experiments reveals the stunning problems that physics can solve.
College Physics I : Mechanics
The first part of College Physics covers the basic concepts of measurement, kinematics, dynamics, momentum, work and energy, rotation, dynamics of rotation, and fluid mechanics.
Teaching Methods:
This online course provides situational approaches. For example, the electronic whiteboard was used as a supplement to follow the same rhythm as contact lectures, and I also demonstrate the phenomena while delivering the topics. You can also watch the demonstration experiments individually in video recordings. Particularly for those who can't take class in real classroom, we have created a small online interactive classroom over Tencent Meeting (schedule see announcement). We adopt more teaching methods, like face to face interaction, group discussion, and focus on the key points and difficulties of each chapter.
Physics is fantastic! The goal of this course is to pass on the physicists' idea of understanding nature to the students at the deepest level and in the simplest way.

Physics is a discipline that studies matter, energy, and their interactions. Its principles are the source of technology, the support point of multidisciplinary crossover, transfer, and penetration. In promoting technological innovation and technological progress, physics plays a leading role. The purpose of the college physics course is to strengthen students' innovative spirit, entrepreneurial awareness, and innovation and entrepreneurial ability. The goal is to help students become talents, and professionals. With the teaching philosophy of "solid foundation, strong ability, emphasis on innovation, and visible results", it is an important general compulsory basic course.
This course is aimed at non-physics major international undergraduates in engineering, aiming to lay a solid physical foundation for the cultivation of non-physical professional engineering and technical talents. After successfully completing this course, students should be able to develop the physical thinking characteristic, such as model thinking, graphical thinking, analogy thinking, equivalent thinking, critical thinking, reverse thinking, isolation thinking, conservation thinking, limit thinking, statistical thinking, hypothetical thinking and many more; to thoroughly understand the basic concepts of physics and the methods scientists use to explore the natural phenomena; to solve problems with relevant mathematical models and formulae.
Learning this course well is not only very important for students' study in school, but also has a profound impact on students' work and progress after graduation, learning new theories and technologies, and constantly updating knowledge, so that students can play their full potential in the future job and market competition.
