FAQs on Important Questions for CBSE Class 9 Science Chapter 9 - Gravitation
1. State the difference between the mass of an object and its weight?
The differences between the mass of an object and its weight are that the mass is the quantity of matter in the body, whereas the weight is the force of gravity acting on the body. The mass is the measure of inertia of the body, and the weight is the measure of gravity. The mass has magnitude, whereas weight has magnitude as well as direction. Mass is a constant quantity, and weight is not a constant quantity. It is different in different places. The SI unit of mass is the kilogram (kg) and the SI unit of weight is Newton (N).
2. What are the benefits of Gravitation Class 9 important questions?
The important questions on the gravitation chapter give an in-depth idea about the chapters and the question patterns that will come in the science exam. These questions are selected from previous years’ question papers and the answers are drafted by subject matter experts at Vedantu. Solving the questions papers will benefit the students to prepare adequately for their exams, understand the subject, and score better marks in the exam.
3. How do you solve the questions of Class 9 Chapter Gravitation of Science?
It is easy to solve the problems in Class 9 of the chapter Gravitation after you understand the theory and derivation of the different formulae. Once you are knowledgeable about the ideas, it will be a gentle cruise to practise the numerical problems. There are a number of formulas in the chapter that you might find difficult to understand the applications. Hence, to resolve your doubts, you can refer to NCERT Solutions by Vedantu (vedantu.com) and Review Notes.
4. What is gravitation?
Gravity, also known as gravitation, is the force that pulls two bodies (that have mass) together.
The chapter is important from the perspective of the exams; hence, it is recommended you solve all the numerical questions. The important questions provided by Vedantu can be a great aid to you for preparing and revving the chapter. Since these questions cover all the fundamental topics, you will have near to no burden of missing out on any vital concept.
5. What is the acceleration due to gravity according to the Chapter Gravitation from Class 9?
Acceleration due to gravity is the acceleration experienced by a body during free fall. It is denoted by ‘g’ and measured in m/s². There are numerous numericals based on the formulas under this topic. The numerical problems are often worded in a twisted manner and can confuse the students, so it will be beneficial to solve them all to learn the application of the formulas correctly in each question.
6. Explain buoyancy with an example.
Buoyancy is the overall upward force exerted on an object that is immersed in a fluid. This happens because of the pressure of the fluid. For example, a wooden plank floats in water. There are many other examples of buoyancy that we experience in our day-to-day life. You can learn more about them in the chapter itself. It is vital to learn the definition word by word so you retain the keywords in it.
7. Is Chapter 9 of Class 9th Science difficult?
Gravitation is a chapter that contains ideas related to our daily lives. When you link the content to things you already do, it is much easier to learn and retain the concepts in the chapter. Though the numerical portion of the chapter may be difficult to grasp, the chapter as a whole is simple to understand. You can get a fine grip on numerical problems by practising them on a regular basis.
