我想問下,一樣野質量高,係唔係會有更多的力(萬有引力)將佢吸向地下??

✔ 最佳答案
係架係地球黎講
地球對佢既吸力=Mass(質量) x g(向心加速度)(9.81)
其實可以用萬有引力公式證明2件物件中互相的吸力 (可能深左少少)
Fg=G Mm/R^2
M係一物件既mass m係另一物件的mass
R係2者的距離
G 係一常數(萬有引力常數)=6.67x 10^11
因為地球質量不變 所以地球對物件既吸力,係同物件既質量成正比!
應該冇錯

Because :
F(Force) = m(mass) x g(gravity) x h(height)
Therefore :
The force when arriving the ground is affected by the mass of the material.
F(Force) = m(mass) x g(gravity) x h(height)
Therefore :
The force when arriving the ground is affected by the mass of the material.
