Introduction to gravity
Have you ever seen an apple falling from a tree? It is a common sight in apple- growing areas and farms. However sometimes a common sight may spark a great idea in an intellectual mind of a genius.it is said that this sight of a falling apple resulted ISAAC NEWTON to realize that all objects are attracted towards the center of the earth.
NEWTON concluded that not only the earth, but every object in this universe attracts every other object present around it with a certain amount of force. To draw this conclusion this great physicist also gave many laws like “THE UNIVERSAL LAW OF GRAVITATION”. …show more content…

Thus, gravitation has a direction along with magnitude. The magnitude and direction of the gravitational force acting between two objects was proposed by the universal law of gravitation. This law was formulated and given by Newton himself.
The universal law of gravitation The gravitational force of attraction between any two object or particles is directly proportional to the product of the masses of the two objects and is inversely or indirectly proportional to the square of the distance that exist between the particles. The direction of this force is along the line joining the two particles.

As the stone moves in this circular path, the direction of the velocity changes continuously. Magnitude of the velocity may or may not change. This means that the stone has some acceleration. By Newton’s second law of motion we can conclude that a certain amount of force is acting on the stone. This force is the cause of the acceleration and continuous change in direction of the stone. I am sure that you are wondering and thinking about who exerts this force? And what is the direction of the force? Well... This is justified. The answer to these questions is given

    In 1687, Newton published Philosophiae Naturalis Principia Mathematica (also known as Principia). The Principia was the “climax of Newton's professional life” (“Sir Isaac Newton”, 370). This book contains not only information on gravity, but Newton’s Three Laws of Motion. The First Law states that an object in constant motion will remain in motion unless an outside force is applied. The Second Law states that an object accelerates when a force is applied to a mass and greater force is needed to accelerate an object with a larger mass. The Third Law states that for every action there is an opposite and equal reaction. These laws were fundamental in explaining the elliptical orbits of planets, moons, and comets. They were also used to calculate

    Newton’s second law states that when a net force is applied to an object, that object will experience a change in velocity, and will undergo acceleration. That acceleration is proportional to the net force applied, and inversely proportional to the mass of the object. In other words, the heavier an object is, it will require a greater force to move the object the same amount (e.g., distance) as a lighter object. ( https://www.grc.nasa.gov/www/k-12/airplane/newton2.html)The mathematical equation that expresses Newton’s second law is:

    Newtons second law can be indentified more easily using the equation F=ma. This is an equation that is very familiar to those of us that wish to do well in any physics class! This equation tells us many things. First it tells us the net force that is being exerted on an object, but it also tells us the acceleration of that object as well as its mass. The force on an object is measured in Newtons (I wonder where they got that from). One Newton is equal to one (kg)(m)/s^2. For example, if superman pushes on a 10,000kg truck and it is moving at a rate of 2m/s^2, then the force that superman is exerting on the truck is 20,000N. For those of us that wish to move on in the field of physics, Newtons second law (F=ma) will forever haunt us!

    Sir Isaac Newton made an enormous amount of contributions to the world of physics. He invented the reflecting telescope, proposed new theories of light and color, discovered calculus, developed the three laws of motion, and devised the law of universal gravitation. His greatest contribution to physics was the development of the three laws of motion. The first law was called the law of inertia; this law stated that, “Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it.” The second law is called the law of acceleration; this law stated that, “Force is equal to the chan...

    The Enlightenment characterizes a philosophical movement of the 18th century that emphasized the use of reason to analyze and scrutinize all previously accepted traditions and doctrines. Through this application of scientific method to all aspects of life, the role of science gradually replaced the role of religion. Sir Isaac Newton, quite possibly one of the most intelligent men to exist, played a key role in the development of the enlightenment. He supplied the foundations on which all sciences since him have been built. Without science and reason the enlightenment would have been unthinkable. In fact, historians quote the publishment of Newton's masterpiece Principia in 1687 as the most logical and fitting catalyst to the enlightenment. The scientific advances made by Sir Isaac Newton contributed immensely to the movement of the enlightenment; however, his primary purposes for discovery were not for scientific advancement rather all for the glorification of God, thus Newton's incredible religiousness will be seen in this paper.

  • What Is Gravity?

    1136 Words  | 3 Pages

    Einstein and Newton are the most popular explanations of gravity to this day. After Einstein, there have been some new theories trying to disprove him. One new popular theory is called emergent gravity and it tries to explain the motions of stars in space. There are many conceptions about gravity that confuse many people. Many people believe space does not have gravity, which is understandable however this is false. Another common misconception is that objects that are farther apart have a strong gravity pull on each other, Newton proved this to be incorrect (“Gravity Misconceptions”). The simple basics of gravity are understood by scientists, but there is still no exact answer that explains just how gravity

    If a force acts on a body, the body accelerates in the direction of the force. In the example of the force of gravity, small things like textbooks are pulled downward toward the center of the large mass of the Earth, not up into space, even if some people think that this might happen.                       Isaac Newton was the first to conceive of weight as the gravitational attraction. between the body and the Earth. The force that results from the gravitational attraction of the Earth on its surface is what we call weight. Science has chosen to measure the mass of objects in units that are roughly equivalent to the weight of those objects on Earth.

  • More than Just Newton and the Apple

    976 Words  | 2 Pages

    As the familiar story goes, Sir Isaac Newton was lounging under an apple tree on a beautiful day in the seventeenth century. Without any warning, a rogue apple fell from a high branch and struck him on the head. Despite the resulting head trauma, Newton spontaneously concluded that some force, which he named gravity, must have caused the apple to fall and thus he formulated his Universal Law of Gravitation. According to Newton, gravity acted as an instantaneous attraction between two objects that could occur over a distance of any size. He developed equations that predicted the effects of gravity with astonishing accuracy, from the falls of apples to the orbits of planets (Strobel). However, Newton’s profound achievement lacked one key aspect. Despite consistent verification by experimental data, it made no effort to explain the mechanism by which gravity operated; Newton said nothing about why gravity worked or how it kept the moon in a perpetual orbit around the earth. He explicitly stated, “I leave this problem to the consideration of the reader,” when referring to the possible causes of gravity (Greene 64). Newton consistently sidestepped this issue, which remained unsolved until the twentieth century.

  • Meaning and Importance of Physics

    727 Words  | 2 Pages

    In the natural world, physicists find new discoveries constantly. Some of these discoveries include the study of motion and forces. The well-known scientist, Isaac Newton, came up with the three laws of motion, which state rules and facts about the movement of an object. Our textbook states the laws of motion, as ?A body in motion will remain in motion at a constant speed and direction unless an outside force acts upon it. The net force acting upon an object is directly related to the mass and acceleration of the object resulting acceleration is in the direction of the net force, which is the vector sum of all forces acting upon the object. Finally, the third law of motion states that when one object applies a force to another, the other object applies the same amount of force back to the first object, but in opposite directions.? With these laws of motion, we can understand in detail how our world works. Also, that the movement of an object is more complex than a simple push. This discovery is taught to students all over the world because of its great importance and will continue to enhance the knowledge of the mystery of our earth.
