在高中物理学习中,不少同学认为题做得越多,解题能力就越强,实则不然。物理题确实要做,但并非越多越好,要讲究适度。在物理解题中,同学们要注重一题多解,通过对典型问题的深入分析和多向思维,敢于打破常规,另辟蹊径,善于联想迁移、纵横发散、对比归纳、引申推导、灵活变通,从而发散思维,开拓思路,提高物理解题能力。例1:如图1所示,物体m用线通过光滑的水平板上的小孔与钩码M相连,并且正在做匀速圆周运动,如果减小M的质量,
In high school physics study, many students think that the more questions are done, the stronger the ability to solve problems, but in fact not the case. Physical problems really do, but not the better, pay attention to appropriate. In physics problem solving, students should pay attention to one problem and multiple solutions. Through the in-depth analysis and multi-directional thinking on typical problems, they dare to break the routine, find new ways, be good at moving the association, diverge vertically and horizontally, derive and deduce, derive and deduce, and thus flexible. Divergent thinking, explore ideas, improve the ability of physical problem solving. Example 1: As shown in FIG. 1, the object m is connected with the hook code M through a hole in the smooth horizontal plate by a thread, and is performing uniform circular motion. If the mass of M is reduced,
