摘要
用GeoGebra软件中的向量作出力的图示不仅精准而且还有动态变化的特点,在动态平衡问题中应用特别常见.四力或四力以上物体平衡时则要采用正交分解法,在GeoGebra中可以通过点的横、纵坐标来实现正交分解.
Force diagrams created by the vector function of GeoGebra are precise and have the characteristic of dynamic change,which is commonly used to deal with the problems of dynamic equilibrium.Orthogonal decomposition method is adopted to analyse equilibrium of four forces or more,and that can be done with the horizontal and vertical coordinates of point in GeoGebra.
