Chapter 10, Gravitation, NCERT Grade 9 Science CBSE belongs to the Unit III Motion, Force and Work. The solutions given to the questions for the in between exercises and exercises given at the end of the chapter are prepared by our subject matter experts in a simple and precise manner.Â In Chapters 8 and 9, we have learnt about the motion of objects and force as the cause of motion. Students are thus, aware of force is needed to change the speed or the direction of motion of an object. However, Chapter 10 of NCERT Grade 9 Science CBSE takes the students to further into the depths of motion of objects under the influence of gravitational force on the earth.
Â
The topics given under the head of Gravitation which is further divided into Universal Law Of Gravitation, Importance of the universal law of gravitation is explained with the help of explanatory content, solved numerical and out of the box information. The topics such as Free Fall including to calculate the value of g, motion of objects under the influence of gravitational force of the earth further explain the concept of motion. These topics are accompanied with elaborative and interactive activities, diagrams and solved numericals. The solutions to the questions for in between exercises will help the students to understand the concept better.
Â
Wonderful explanation of the topic Mass weight, weight of an object on the moon will be learnt in this chapter with the help of solved numerical problems.Â In the chapter, Gravitation, students will also learn Thrust and Pressure.Â The pressure in fluids, buoyancy, why objects float or sink when placed on the surface of water? The topics Archimedesâ€™ Principle and Relative Density describes important concepts such as theory given by Archimedes and density of a substance with respect to density of water. Solutions given for the revision questions given under the heads of different activities and in between exercises further help in reinforcing the concept to the learner and will help them in scoring well in the exams. This chapter is a part of Unit III, Motion, Force and Work of NCERT Grade 9 Science CBSE and holds a weightage of 27 marks in the final examination.
