**Who invented gravity, Newton’s Three Laws, Galileo experiments**. Naturally, since ancient times, humans had a basic understanding of this force. And when it comes to our modern understanding of gravity, its credit is given to a person who has blamed its qualities and how it makes all things great and small -

**Sir Isaac Newton**17th Century English Thanks to physicist and mathematician, our understanding is the universe and the laws governing it.

## Who Invented Gravity?

While all of us are familiar with the iconic image of a man sitting under an apple tree and after falling on his head, Newton's theories on gravity also represented a culmination of years worth of research, which in turn would help in accumulated knowledge Was on the basis of centuries. These principles will be presented in their Magnum Opus, Philosophy Naturalism, Principia Mathematica ("Mathematical theory of natural theory"), which was

**first published in 1687**.

## Sir Isaac Newton

**Isaac Newton was born in England in 1643.**As a young man, he went to Trinity College in Cambridge, enrolled as a student for the first time, and eventually started living as a partner. During this period, he developed earlier versions of his three laws of motion, including the law of gravitation. During his career, he made significant progress in understanding the field of optics and centrifugal force. He eventually became the first English scientist to become a knight for his work.

## Exploration of Gravity

A popular story tells that Newton came immediately with the theory of gravity when an apple fell from a tree and hit it on the head. In fact, Newton saw an apple falling from a tree, and found it to think about the mysterious power that pulls objects on the ground. They compared the direct route of apple to the curved path of a wired gun. They thought that if the cannon ball moves faster and faster, then what will happen and they will realize that it will "fall" around the earth forever, and will never collide with the ground. It is the movement of the earth around the Moon and the Sun around the Earth, at the speed of "falling forever".

## Newton’s Three Laws

In 1678, Newton faced a completely nervous breakdown due to a fight with overwork and fellow astronomer Robert Hook. For the next few years, he withdrew from correspondence with other scientists, where he started it, and renewed his interest in mechanics and astronomy. In the winter of 1680-81, the presence of a comet, about which he corresponded with John Flamested (the Astronomer Royal of England) also renewed his interest in astronomy.

After reviewing Kepler's law of motion,

**Newton developed**a mathematical proof that the elliptical form of the orbits of the planets would result in the proportional force in contrast to the square of the radius vector. Newton conveyed these results to Edmund Halley (the explorer of "Heli's comet") and in the Royal Society, in his De Motu Corporation, Guerrum.

In this tract published in 1684, Newton was expanded in the form of his Magnum Opus, Philosophie Naturolis Principia Mathematica. This book, published in July 1687, included three rules of Newton's motion, which stated:

- When an inertial reference is seen in the frame, an object either remains at rest or keeps moving at a constant speed until it is done by external force.
- The vector sum of the external forces (F) on an object is equal to the mass (m) of the object which is multiplied by the acceleration vector (a) of the object. In mathematical terms, it is expressed in this form:
**F = Ma.** - When a body imposes a force on one another, then the other body increases one force together in magnitude and is opposite in the direction of the body first.

## Galileo Experiments

If Ibn al Hayatam refused to completely deny Ptolemy's theories, Galileo did not have such a property. He was born in 1564 in Pisa, Italy and became one of Renaissance's most notorious and ultimately influential thinkers. While the comments of Democrats and Ibn al-Haitham underlined the theory of gravitation, Galileo's work directly communicated it. He rejected the rights of both Aristotle and Ptolemy, became a pariah in the eyes of the Catholic Church and the scientific establishment. Most relevant to gravity, he said that gravity works on objects regardless of its mass; Due to the different size, due to the resistance of the wind, the difference in the result of a drop, not the weight.

**Galileo is said**to have said that he had dropped balls of the same size but had a weight different from the Leaning tower of Pisa, and although the story could be apocryphal, the resulting theory is at the center of gravitational theory.

## Newton's Apple

Another apocryphal story underlines Newton's work; Famously, the great mathematician was motivated to study gravity when an apple fell on his head. Born in 1642, Newton was only in his Forties, when he published his most influential book, "Philosophy Naturalism Principia Mathematica", which was often known as "Principia". Galileo Newton's Newton tested the principles of contemporary astronomer Johannes Kepler. Three rules of motion, which deal with inertia and mechanics as well as its theory of gravitation; This principle states that every object in the universe attracts every other object in proportion to its mass. Although this theory, modified by Albert Einstein and later physicists, still indicates scientific thought, mechanical engineering, and astronomy.
