定性探究动能表达式的实验是定量探究和理论探究的铺垫实验,不需要准确数据,只需要实验现象和结论能简洁直观地验证猜想即可。在平时教学中,笔者设计了如下实验来定性探究动能的表达式。一、实验目的定性探究小钢球的动能表达式。二、实验原理
The qualitative experiment of kinetic energy expression is a foreshadowing experiment for quantitative inquiry and theoretical inquiry. It does not need accurate data, only the experimental phenomena and conclusions can concisely and intuitively verify the conjecture. In normal teaching, I designed the following experiment to qualitatively explore the expression of kinetic energy. First, the purpose of the experiment Qualitative exploration of small steel ball kinetic energy expression. Second, the experimental principle
