Detailed explanation-1: -Legend has it that Isaac Newton formulated gravitational theory in 1665 or 1666 after watching an apple fall and asking why the apple fell straight down, rather than sideways or even upward.
Detailed explanation-2: -It states that: “he first thought of his system of gravitation which he hit upon by observing an apple fall from a tree". The event occurred in the late summer of 1666. Other accounts state that Newton was sitting in his garden at Woolsthorpe Manor when the event occurred.
Detailed explanation-3: -There’s no evidence to suggest the fruit actually landed on his head, but Newton’s observation caused him to ponder why apples always fall straight to the ground (rather than sideways or upward) and helped inspired him to eventually develop his law of universal gravitation.
Detailed explanation-4: -In 1687 English physicist Sir Isaac Newton (1642-1727) published a law of universal gravitation in his influential work Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy).
Detailed explanation-5: -“Aha!” he shouts, or perhaps, “Eureka!” In a flash he understands that the very same force that brought the apple crashing toward the ground also keeps the moon falling toward the Earth and the Earth falling toward the sun: gravity.
