# Summary of GRAVITATION in 1 Shot: FULL CHAPTER COVERAGE (Concepts+PYQs) || Prachand NEET 2024

The video, presented by Prachand, a YouTube educator for NEET 2024 preparation, provides a comprehensive coverage of the concept of gravitation. Various topics related to gravitation are discussed, including Newton's Law of gravitation, gravitational force, and gravitational field. The Babli method is used to explain concepts, with a focus on direct application of formulas and concepts. The calculation of forces and distances in different geometric shapes like triangles, squares, and hexagons is covered, along with the concept of vector addition and subtraction in different scenarios to calculate forces accurately.

- The video delves into the calculation of forces between particles, the concept of null points, and the application of gravitational force in different scenarios.
- The importance of understanding physics concepts thoroughly and practical aspects of studying for exams like NEET are emphasized.
- Trivia questions are included to test the viewers' understanding of the material.

## Further Details

Furthermore, the concept of gravitation is detailed, explaining the gravitational force between masses, the motion of objects in space, and the effects of gravity at different distances from the Earth's center. The gravitational force is proportional to the product of masses and inversely proportional to the square of the distance between them. The video also discusses weightlessness at the equator due to the rotation of the Earth, calculating the effective gravitational force at the equator as the difference between the normal gravitational force and the centrifugal force due to the Earth's rotation. The time taken for an object to appear weightless at the equator is calculated using a specific formula.

- The speaker focuses on the time period of a pendulum, the value of gravity, and the significance of the number 84.6 in gravitation calculations.
- Different scenarios like spinning and flying are presented to explain the concept of time period in gravitation, along with discussions on how the value of gravity varies at different locations on Earth's surface.
- Various calculations and formulas related to gravitation, including the value of 'g' at different locations, jumping on different planets, and the impact of gravity on height and time, are explained.

The concept of energy in gravitation, potential energy, and calculations involving multiple masses and distances are also covered. The speaker concludes by discussing personal aspirations and the importance of perseverance in learning.
