Sir Isaac Newton Science


Sir Isaac Newton Science

Sir Isaac Newton was an English physicist, mathematician, and astronomer, who is widely considered as one of the most influential people in human history. His 1687 publication of the PhilosophiƦ Naturalis Principia Mathematica (usually called the Principia) is considered to be among the most influential books in the history of science, laying the groundwork for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion which continues an important role in the scientific view of the physical universe for the next three centuries. Newton also built the first practical reflecting telescope and developed a theory of colour based on the observation of a prism. He also formulated an empirical law of cooling and studied the speed of sound. I like to share this heat capacity equation with you all through my article.



Sir Isaac Newton's Science:


Newton investigated the refraction of light, demonstrating that a prism could decompose white light into a spectrum of colours, and that a lens and a second prism could do the reverse.

His studies proved that coloured light does not change its properties by separating out a coloured beam and shining it on various objects. Newton noted that regardless of whether it was reflected or scattered or transmitted, it stayed the same colour. Thus when objects interact with already-colored light, colour is produced. This is known as Newton's theory of colour. From this work, he concluded that the the dispersion of light into colours can be seen in lens of any refracting telescope. Newton’s contribution to the Law of Gravity is phenomenal and is regarded one of the major break-throughs in the world of Science.



Sir Isaac Newton’s Laws of Motion:


The famous three laws of motion are:

Sir Isaac Newton's First Law (also known as the Law of Inertia) states that an object at rest tends to stay at rest and that an object in uniform motion tends to stay in uniform motion unless acted upon by a net external force.

Sir Isaac Newton's Second Law states that an applied force on an object equals the rate of change of its momentum, with time.

Sir Isaac Newton's Third Law states that for every action there is an equal and opposite reaction
