Gravitation is important from the perspective of scoring high in IIT JEE, AIEEE and other engineering examination as the questions based on them are direct and do not have much twist and turns. You are expected to do all the questions based on this to remain competitive in IIT JEE examination. It is very important to master these concepts at early stage as this forms the basis of your preparation for IIT JEE, AIEEE, DCE, EAMCET and other engineering entrance examinations.
One of the most profound mysteries of nature is - why objects fall down?
This was first solved by Sir Isaac Newton in the seventeenth century - it is known as "the law of gravitation". Gravitation is one of the four fundamental forces of nature. If acts between all material bodies in the universe - it is universal.
This chapter deals with the universal law of gravitation, Gravitational field, Gravitational potential energy and gravitational potential, Acceleration due to gravity, Kepler's law, Motion of planets and satellites in circular orbital and elliptical orbit in great detail with solved examples.
"Gravitation" is one of the easiest and important chapters of Mechanics in the Physics syllabus of IIT JEE, AIEEE and other engineering examinations. These laws are not new to any aspirant as he is reading a number of stories about apple falling on the head of Sir Issac Newton. The examples based on this are very easy and can be seen even in day to day life.
The chapter is important not only because it fetches 3-4 questions in most of the engineering examination but also because it is prerequisite to the other topics of Physics like Heat, Electro-magnetism and Modern Physics.
