What is the law of universal gravitation? Why is gravitational attraction not the same everywhere on
the surface of Earth? What will be an ideal response?
Isaac Newton said that the force of gravity (F) between two masses (m1 and m2) is directly
proportional to their masses and inversely proportional to the square of the distance between their
centers of mass. This means that an attractive force exists between any two objects and the magnitude
of that force varies, depending on the masses of the objects and the distance between their centers.
Gravitational attraction would be the same everywhere on Earth's surface if the planet were perfectly
spherical, homogeneous throughout, and not rotating. But none of these things is true.
