Research On The "Pull" Problem Related To Rope Model

At present,some teacher and scholar have problems at “pull” process,fallacious thinking “pull” and hit those Two different physical processes as one thing,and have disagreement at the specific nature of “pull”,there are variety errors examples answering examples of "pull".This article will study the nature of “pull”,and compare the similarities and differences between the “pull” problem and the hit problem,sum up the “pull” problem solving norms.At the same time,study two representative examples in the light rope “pull” and the quality of the rope “pull”.Finally,put forward some suggestions about relevant knowledge of physics teaching materials and the teaching of rope model.
