explain the universal law of gravity and its calculated from as well as the value of g.
Answers
Answer: Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
Newton’s conclusion about the magnitude of gravitational forces is summarized symbolically as
F=Gm1m2r2
where,
F is the gravitational force between bodies
m1 is the mass of one of the objects
m2 is the mass of the second object
r is the distance between the centres of two objects
G is the universal gravitational constant
