为什么地球吸引物体？
地球吸引物体，主要基于以下几个原因：
1、万有引力定律：根据牛顿提出的万有引力定律，任何两个物体之间都存在吸引力，这种力与两个物体的质量成正比，与它们之间的距离平方成反比。地球的质量远大于地面上的物体，因此地球对物体的吸引力显著。
2、地球的质量：地球的质量非常大，这使得其引力场强度足以吸引地表及附近的所有物体。这种引力指向地心，是物体“下落”的根本原因。
3、地球自转产生的惯性离心力：虽然地球自转会产生一定的惯性离心力，但其影响相对较小，主要作用是略微抵消地球引力。在赤道附近，惯性离心力最大，但总体上仍无法完全抵消地球的引力。
总结：地球吸引物体的根本原因是万有引力定律，这种力与地球的质量密切相关，并指向地心。尽管地球自转会产生惯性离心力，但其影响有限，地球引力仍是主导因素。
