1. When apple falls, Gravitational force does not increase as the apple's mass is increased, or replaced by a heavier fallen object. so small m should be removed from the formula.
2. When the pulled object is a star, planet, or moon, The final net force is Fg1-Fg2, because pulled object also has its gravity.
3. /R is more effective and more understandable than /(R^2). because physics formula are by directly relationship and inverse relationship, so many make sense.
1. 當蘋果落下時，隨著蘋果質量的增加，或墜落物體變成更重的物體，重力不會增加。
因此,小的m應該從公式中刪除。
2.當被拉物體是星球，行星或月亮時，最終的淨力是Fg1-Fg2，因為被拉物體也有其重力。
3. / R比/（R ^ 2）更有效，更容易理解。 因為物理公式是，通過正比和反比關係，所以很多都可以被公式接受。
