Newton's laws are often stated in terms of point or particle masses, that is, bodies whose volume is negligible. This is a reasonable approximation for real bodies when the motion of internal parts can be neglected, and when the separation between bodies is much larger than the size of each.
Coulomb's law has charge in place of mass and a different constant. Newton's law was later superseded by Albert Einstein 's theory of general relativity , but the universality of the gravitational constant is intact and the law still continues to be used as an excellent approximation of the effects of gravity in most applications.
In physics, a number of noted theories of the motion of objects have developed. Among the best known are: Classical mechanics. Newton's laws of motion; Euler's laws of motion; Cauchy's equations of motion; Kepler's laws of planetary motion ; General relativity; Special relativity; Quantum mechanics
Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2]
Newton's laws of motion, three physical laws that, together, laid the foundation for classical mechanics; The laws of thermodynamics, originally three physical laws describing thermodynamic systems, though a fourth one was later formulated and is now counted as the zeroth law of thermodynamics

Although the laws of motion and universal gravitation became Newton's best-known discoveries, he warned against using them to view the Universe as a mere machine, as if akin to a great clock. He said, "So then gravity may put the planets into motion, but without the Divine Power it could never put them into such a circulating motion, as they ...
