Problem solving of Newton’s second law through a system of total mass motion

The use of strategy of total mass motion is one way to comprehend the application of Newton’s second law in various motion systems. This strategy is appropriate to be used in fundamental physics lecture for year one university student. This is because the students have already basic knowledge about Newton’s second law from high school, so that at the university level the application of the law can be given directly. By given more exercise of physics problems student will strengthen their understanding of the subject, and the solution using strategy of total mass motion is an effective way in improve students comprehension on the application of principles, laws, and formulation comprehensively.

However STMM has limited its use. STMM only be used for cases of force and motion straight, while for cases such as momentum, equilibrium systems, rolling motion, vibration, and other topics are very difficult to implement.
