, 3.1 Newton’s Universal Law Of Gravitation
A. Gravitational force
Newton’s Universal Law of Gravitation
state that
Gravitational force, F is directly proportional to the product of mass of the object and inversely
proportional to the square of the distance between them
FORMULA
F = Gravitational force between
two objects
𝐺𝑚! 𝑚# G = Universal gravitational
𝐹=
𝑟# constant
(6.67 x 10-11 N m2 kg-2)
m1 = mass of first object
m2 = mass of second object
r = distance between the center
of two objects
Factor that affect gravitational force
mass of object, m distance between objects, r
