| Abstract: | In the mechanics part of University Physics several laws and theorems are frequently used, such as the laws of Newton, the theorem of momentum, the principal of conservation of momentum, the work-energy theorem, the law of conservation of mechanical energy etc. These reflect the basic laws of moving object and provide the key and principle of solving the mechanics problems. Among all laws Newton's second motion law is the most important and foundational, the others can be deduced by means of apt transformation. In this paper the relations among mechanics basic laws and conditions of each law or theorem established are found through the study on Newton's second motion law. It is handy for correct applying these laws and theorems to solve the relevant problems of physics. |
