What is phenomenon of gravity
To understand gravity, we must delve into the realm of Newtonian physics and explore the intricate relationship between mass, distance, and gravitational force. Newton's laws of motion provide the foundation for our understanding of how objects move, while his law of universal gravitation explains the nature of the gravitational force between two objects.
According to Newton's first law of motion, an object at rest will remain at rest, and an object in motion will continue moving in a straight line at a constant velocity unless acted upon by an external force. This principle reveals that objects tend to maintain their state of motion unless influenced by an external force, such as gravity.
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. This equation, F = ma, shows that a force acting on an object will cause it to accelerate, with the magnitude of acceleration depending on the strength of the force and the object's mass.
However, it is Newton's law of universal gravitation that uncovers the nature of the force responsible for the attraction between objects with mass. The law states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Mathematically, this can be expressed as F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.
This equation demonstrates several essential aspects of gravity. Firstly, the force of gravity is always attractive, meaning that it pulls objects towards each other rather than pushing them apart. Additionally, the
