kalau ikut ilmu sains modern
objek itu , w = mg  ,  kuasa ke bawah
w Weight , m = mass , g = acceleration of gravity

w = vpg

Buoyancy Force (daya keapungan) = pvg   , kuasa ke atas
Fa , daya keapungan = Ketumpatan, p X   isipadu,v  x  acceleration of gravity , g
Fa = vpg

kuasa objek w vs daya keapungan Fa =   w = vpg    vs   Fa = vpg  

g akan dipotong , v juga akan dipotong(kecuali yg kejadian terapung)

g itu tak perlu ada

dalam matematik ini ,  g , gravity itu tak peru wujud



jadi , sesuatu benda terapung , melayang atau tenggelam dalam air atau di udara , tak ada kaitan dgn kuasa gravity .
