The great scientist Newton’s full name was Sir Isaac Newton Sir Isaac Newton. Newton was born on Christmas Day 25 December 1642 in Lincolnshire, England, and his size was very small at birth. Newton was born 3 months after the death of his father Isaac Newton. His father’s skilled farmer and his mother’s name was Hannah Escuff. Newton lived with his grandmother Margherie Aescough at the age of three because her mother had married another.
By the age of 12 to 17, Newton received education at The King’s School, Grantham, when he was expelled from school, he came to his mother in ‘Woolsthorpe-by-Colsterworth’ in October 1959.
In June 1661 Newton was admitted to Trinity College, Cambridge as a czar. At that time college education was based on Greek philosopher Aristotle. But Newton wanted to read the ideas of modern philosophers and astronomers like Copernicus, Galileo and Kepler.
Gravitational Force Gravitational Force.
Newton one day was sitting under the apple tree. Only then did an apple fall on his head, from this incident Newton was born in the mind of a curiosity that why did this apple finally fall down? Why did not it go upwards? After this, Newton began to discover that what is the reason for this that why things fall downwards?
After some years Newton discovered that there is an attraction force in the earth that draws all things towards it. Isaac Newton named this property of the Earth as ‘Gravitational Force’. Because of this force, the earth and all the planets are rotating around the sun and life on our earth is possible.
Newton pointed out that due to the fact that all the planets are bound by their own gravitational force, the universe has stability. Galaxies and stars have been formed due to the force of gravity, it is possible to have sea and atmosphere on earth.
Newton’s Three Laws of Motion.
1.Newtons first law.
According to the first rule, an object which is in constant state. He will remain stable and an object which is in the same state of motion, will continue to move in the same direction with the same speed, unless an external force acts on it.
2.Newton’s second law.
The force applied to an object is equal to the rate of change in its momentum over time.Since the second rule applies to the object of a fixed mass. The first term (dm / dt = 0) is vanished and by using the definition of acceleration, the equation can be written as follows in the form of signals.
F = ma
The first and second rules represent the breaking of Aristotle’s physics, in which it was believed that a force is necessary to maintain the speed.In respect of Newton, SI unit of force has been named ‘Newton’.
3.Newton’s Third Law
Each action has an equal and opposite reaction. This means that whenever one object puts one force on another object then the other object imposes the same force on the first object in the opposite direction.
For example, to feel the back and push of the gun, in which the force applied to it to fire the bullet, puts an equal and opposite force on the gun, which seems to be a bullet.
Unlike Aristotle, the physics of Newton became universal. For example, the second rule of motion also applies to planets and a falling stone. The vector nature of the second law of motion establishes a geometrical relationship between the direction of force and the type of change in the momentum of the object.
Other discoveries of Newton.
Newton discovered the law of gravitational force and speed, and in 1687 a research paper of “Mathematical principles of natural philosophy” was published. In this, universal gravity and rules of motion were explained. In this way the foundation of lasting physics was laid.
In 1687, Newton’s book Philosophie Naturalis Principia Mathematica was published, the most influential book in the history of science.Newton’s universal gravity and the three rules of speed established the supremacy of the scientific universe of the physical universe.
Newton established continuity between the laws of planetary motion and the theory of gravitation for the speed of objects on Earth and the control of celestial bodies.Newton established the principles of preservation of momentum and angular momentum in mechanics.
