The law of gravity was first set out by Sir Isaac Newton, the
English physicist and astronomer, in 1684. According to Newton, every
massive body has its own gravitational field (or field of gravity),
which is responsible for exerting an attractive force on other massive
bodies. The gravitational force exerted by one body on another is
proportional to the body’s mass and inversely proportional to the
square of the distance between those two bodies. This means that,
the greater the mass of the body, the more gravity it exerts. And
the further it is from another body, the less gravity it exerts upon
that body.
On Earth, the direction of gravity is constant. Thus in any given
place, all free bodies fall toward the ground.
However, its field of gravity is subject to disparities due to
the variations in composition and topography found in our...
