Gravitation MCQs for NEET

Gravitation is a fundamental force acting between two bodies in space. The law of gravitation states that it depends on the masses of the objects and the distance between them. It is an important chapter, therefore, you will have to develop in-depth learning of the physics multiple choice questions on gravitation before taking up NEET. 

Students often confuse several terminologies included in this chapter. This is where you need to study the chapter thoroughly before delving into the MCQ on gravitation. These questions will act as a self-assessment for you once you have studied the entire chapter.

Law of Gravitation and More 

Gravitation is a force of attraction that binds two objects to stay close to each other. A common example, in this case, is our earth and human beings. The reason why we stay on earth’s surface is only because of gravity, and this law is called the law of gravitation.

So, now that you have a hold on gravitation questions for NEET, thoroughly revising them will help you improve your level of preparation. Simultaneously, you should read and understand the related topics apart from the MCQs. Besides, make sure you also solve the problems included in the chapter.

It will facilitate you with an overall understanding of the chapter. You should note that questions can be asked from anywhere in this section. Hence, studying this entire chapter, along with physics multiple choice questions on gravitation, is the key to scoring higher. 

The NEET exam demands students to be upfront and prompt in solving numerical as well as in theory. So, while you are preparing with physics multiple choice questions on gravitation, ensure you do not miss out on any relevant topic from this chapter.

Therefore, it is advisable that you also go through the entire chapter before and after taking the test on questions on gravitation for NEET. This will help you in building a strong understanding of the chapter right from its grassroots. Revising the same will only add to the power of retaining information for longer.

Multiple Choice Questions on Gravitation - Understanding in Details

The term “gravity” is applied to objects, but gravity is defined as the theory of attraction, while gravity is defined as the force that impels objects. Newton is a unit of gravity.

Gravity between two objects is directly proportional to the product of their mass and corresponds to the square of the distance between their points.

The National Eligibility cum Entrance Test (NEET) is a national medical admission test by the NTA (National Testing Agency) for students who wish to pursue medical studies at all medical colleges in the country. The NEET 2024 questionnaire is based on the syllabus specified by MCI (Medical Council of India).

The NEET syllabus is designed by the MCI after analysing the syllabus specified by the various Provincial boards in addition to the syllabus determined by NCERT, CBSE, and COBSE for Grades 11 and 12 Physics, Chemistry, and Biology to ensure uniformity of medical education throughout. India. Getting acquainted with the syllabus can ensure a complete overhaul of each topic addressed in the 2024 NEET syllabus.
