This video lecture for iit jee physics will help you understand the topic gravitation. In this IIT JEE video for physics, we will talk elaborately on gravitational force, Newton’s law of gravitation, universal gravitational constant and its measurement, the acceleration due to gravity and few example problems. There are four basic interactions in the universe they are;

  1. Gravitational force
  2. Electromagnetic interaction
  3. Strong interaction
  4. Weak interaction

In this video, we will talk about gravitational force, you will learn about rest of the topics in your higher classes. So what is Newton’s law of gravitation?  According to this law, “every particle attracts every other particle with a force which follow inverse square law.” The gravitational constant (G) is an attractive force and is independent of medium and by the presence of absence of other particles between the particles. This jee physics video also explains the Cavendish experiment which was the first experiment to measure the force of gravity. Next iit jee physics topic and the last topic discussed is acceleration due to gravity, which is nothing but the acceleration of the body.

Most of the students find it hard to solve physics, as their basics are not cleared. So for the Students aspiring for competitive exams like IITJEE can find all their problems solved, as we are discussing it from the very basics. In this physics video, we are going find out how F = (-GMm/ r²), and why is it negative and also its vector form. Next, we have derived the value of the gravitational constant (G) which is 6.67 x 10-¹¹ Nm²/kg². The acceleration due to gravity is derived and we found that g = Gm/ r². And in the end, there are solved examples which will help you understand the topic better. Similarly, we can solve all your fear when it comes to solving physics. We are ready to help you out in every way possible, all you have to do is put your faith in us and our videos and you will find the results automatically.
