Explanation:
Newton’s Law of Universal Gravitation
Newton’s Law of Universal GravitationAccording to the Universal law of gravitation, the force between two bodies is directly proportional to their masses and inversely proportional to the square of the distance between them. Mathematically, it is represented as follows:
F∝m1m2r2 ⇒F=Gm1m2r2
where,
where,F is the gravitational force between two bodies
where,F is the gravitational force between two bodiesm1 is the mass of one object
where,F is the gravitational force between two bodiesm1 is the mass of one objectm2 is the mass of the second object
where,F is the gravitational force between two bodiesm1 is the mass of one objectm2 is the mass of the second objectr is the distance between the centers of two objects
where,F is the gravitational force between two bodiesm1 is the mass of one objectm2 is the mass of the second objectr is the distance between the centers of two objectsG is the Universal Gravitation Constant.
where,F is the gravitational force between two bodiesm1 is the mass of one objectm2 is the mass of the second objectr is the distance between the centers of two objectsG is the Universal Gravitation Constant.Henry Cavendish, with careful experiments, found the value of Gravitational Constant to be 6.67 x 10−11 m3⋅kg−1⋅s−2N. The value of ‘G’ remains constant throughout the universe.
