Gravitational force
In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.
Acceleration Due to Gravity
In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.

To find some of the parameters characterizing an object moving in a
circular orbit.
The motivation for Isaac Newton to discover his laws of motion was to
explain the properties of planetary orbits that were observed by Tycho
Brahe and analyzed by Johannes Kepler. A good starting point for
understanding this (as well as the speed of the space shuttle and the
height of geostationary satellites) is the simplest orbit: a circular one.
This problem concerns the properties of circular orbits for a satellite
orbiting a planet of mass M.
For all parts of this problem, where appropriate, use G for the
universal gravitational constant.
