Newton universal law of gravitation and derivation
Answers
Answer:
Every object in this universe attracts every other object with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.
Answer:
let two object A and B of masses M and m lie at a distance small d from each other . let the force of attraction between two objects is F , according to the universal law of gravitation the force between the objecs is directly proportional to the product of their mass
F directly proportion to M*m - eq.1
And force between two object is inversely proportional to the square of the distance between them .
F directly proportional by 1/r^2 -eqn.2
on combining eqn1 and eqn.2
F directly proportion by Mn/r^2
F=G Mm/r^2
where G is constant of proportionality and is called universal gravitation constant .
