 # Gravitation MCQs for NEET

### Multiple Choice Questions on Gravitation - Understanding in Details

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 bind 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 as law of gravitation.

To help you test your understanding, here is a list of MCQ questions on gravitation for class 11. Make sure you have gone through this chapter earlier, and only then you start with this assessment.

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 got 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.
