Inventions and laws of Sir Issac Newton and Johannes Kepler Kepler is Johannes one name that will always be remembered in the field of astronomy. He was not only a great astronomer ,but famous mathematician and astrologer also. The German astronomer was the first person to explain planetary motion. He gave three laws of planetary motion .Which was the basic of Isaac Newton law of gravitation, Sir Issac Newton universally considered to be one of the greatest and most influential scientists .he was an English mathematician and physicist, well known for his contributions to physics and mathematics . He also invented the geometric graph of tangent (differentiation) and formulated the three laws of motion and the universal theory of gravitation. Newton also showed that sunlight is the combination of many colours. Johannes Kepler was born in 1571 in Weil der Stadt (Germany). His father,Heinrich Kepler was a soldier and his mother( Katharina Guldenmann )was a healer and herbalisIn.In 1576 ,Johannes began his schooling first in the German School and then others. In 1583 exam in Stuttgart was given by him and also he passed that .And the following…show more content…
In his first law he explained that. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.In second law he define the force and give the expression F=ma where m is the mass of the body and a is acceleration due to gravity. While in his third law he showed reaction that is F12=-F21 which mean in between each two bodies there is equal and opposite reaction. On the other words it mean that if a person is walking that means he is applying force on earth;whereas,earth also applying force on his foot as much he apply on the
