计算型填空题的特点是根据题设条件,应用物理概念、规律或公式,通过数字或文字运算得出结果,这类题型在填空题中所占比例最大,其综合程度不高、涉及的知识点少,但题目的灵活性强。要求考生在熟练掌握物理原理的基础上,灵活运用物理思维方法,突破常规思维模式,独辟蹊径,迅速求解。能多角度、多方位、多层次考查考生解决实际问题的能力。本文通过对近几年高考计算型填空题的分析和解答,使考生掌握迅速、简捷地解答计算型填空题的方法。例1.(96.21)在光滑水平面上有一静止的物体,现以水平恒力甲推这一物体,作用一段时间后,换成相反方向的水平恒力乙推这一物体,当恒力乙作用的时
Computational-type fill-in questions are characterized by the application of physical concepts, laws, or formulas based on the conditions of the questions, and the results are obtained through numerical or textual calculations. Such question types have the largest proportion of questions in the blank-filling question, and their comprehensiveness is not high. Less knowledge, but the topic of flexibility. On the basis of mastering the physical principles, candidates are required to flexibly use physical thinking methods, break through the conventional thinking model, and find solutions to solve problems quickly. Can examine candidates’ ability to solve practical problems from multiple angles, multiple orientations, and multiple levels. This article analyzes and solves the problems of filling in the blanks of the college entrance examination in recent years, so that the examinee can quickly and simply answer the method of filling in the blanks. Example 1. (96.21) There is a stationary object on a smooth horizontal surface. Now push the object with horizontal constant force A. After a certain period of time, replace it with the horizontal constant force in the opposite direction B. When the constant force B acts When
