Analysis Of Research On Speed Synthesis, Speed Of Composite, The Correlation Speed In High School Physics Teaching

At present, the high school physics teacher for speed synthesis and the understanding of the relative motion velocity in the compound the problems, both as one and the same mistake, and do not have a unified definition of connection speed,speed in solving the problem of connection speed to use the synthesis and decomposition, two methods of relative movement of error-prone. Through the comprehensive comparison and analysis of physical concepts related to the speed of compound synthesis and speed to make a precise, and uniform definition of connection speed for the two linked in some way, the speed of the two speed can be through the media(rope or pole) or is linked to the mutual contact speed ". At the same time, based on the student connection speed problem sets are classified analysis of the relevant solutions. Finally put forward the high school physics about speed teaching link speed synthesis, composite, suggestions for improvement.
