摘要
相同的物体彼此堆叠,形成独立的塔.通过施加突然的水平力来卸下底部物体,以使塔架的其余部分下降到地面上,并且塔架保持直立.本实验将研究该现象并确定允许塔保持直立的条件.从项目本身出发,选择不同形状的物体进行实验,采用控制变量法对块的数量、块的规格,水平力的大小等相关变量进行实验和探究.先利用所学的动力学知识从理论上分析,再进行具体实验得出相关数据.进一步通过对实验结果的分析和建模,建立对其他类似现象的描述.
The same objects stack each other to form independent towers.Remove the bottom object by applying a sudden horizontal force so that the rest of the tower falls to the ground and the tower remains upright.This experiment will study such phenomenon and determine the conditions that allow the tower to remain standing.Starting from the project itself,different shapes of objects are selected for experiments,and the control variable method is used to experiment.The number of blocks,the specifications of blocks,the size of horizontal forces and other related variables are explored.First,the kinetic knowledge is analyzed theoretically,and then the relevant data are obtained by specific experiments.Further the description of other similar phenomena is established through the analysis and modeling of the experimental results.
