物理估算题,是指考生在物理背景和物理过程模糊的问题中,能摒弃次要因素,抓住主要因素和物理本质,建立合理的物理模型,寻求合适的物理规律和数学关系,运用一些常识性的实际知识,建立待求量与已知量的关系,借助“近似估算”的数学知识,进行合理的推算。物理估算题最早出现在1984年的全国高考题中, Physical estimation questions refer to candidates’ ability to abandon minor factors in the ambiguity of physical background and physical process, grasp major factors and physical essence, establish reasonable physical models, seek appropriate physical laws and mathematical relationships, and apply some common sense. The actual knowledge of sex, the establishment of the relationship between the quantity to be known and the known quantity, with the aid of mathematical knowledge of “approximate estimation”, a reasonable calculation. The physical estimation question first appeared in the national college entrance examination question in 1984.
