Can someone please give me the derivation of Newtons Law of Universal Gravitation

Question

ujjwal · Answer

$$F \alpha 1\div r ^{2}$$$$F  \alpha m1*m2$$
from above two relations
$$F \alpha \left( m1*m2 \right)\div r ^{2}$$
or, $$F= G \left( m1*m2 \right)\div r ^{2}$$
where G is universal gravitational constant
m1= mass of 1st body
m2= mass of 2nd body
r= distance of separarion betweeen them

anonymous · Answer

Every body in universe attracts every other body with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance b/w their centers.

$$F \alpha m1.m2$$

$$F \alpha1/r2$$
Combining these two Relation:

u cant derive newtons law of gravitations ! can u ?? its a LAW !! :/ BUT U can tell its directly propotional to mass and inversely to square of the distance ... thats all
