Fav十万个为什么
为什么重力让物体向地面掉落？
1、地球的质量非常大，它产生的引力使得任何靠近它的物体都会被吸引向它的中心，也就是地心。
2、重力是一种自然力，它作用于所有具有质量的物体之间，使得物体相互吸引。
3、地球表面的物体因为受到地球的引力，所以会向地面掉落，而不是漂浮在空中。
4、在地球表面，所有物体都以相同的加速度下落，这个加速度被称为重力加速度，大约是每秒9.8米。
5、重力的作用是普遍的，不仅影响地球上的物体，也影响天体之间的运动，比如月球绕地球转、地球绕太阳转。
总之，重力是地球对物体的吸引力，使得物体向地面掉落，这是地球质量导致的自然现象，也是所有物体在地球表面都会经历的基本物理过程。
