NCERT Solutions for Class 9 Science Chapter 8 Motion

NCERT Science Book  Chapter 8 is a mix of theory and numerical questions. It includes information about motion, rate of change of velocity, the speed with direction and the graphical representation of motion. Equations of motions and numerical problems related to the same are also a part of this chapter. This chapter will also  explain the fact that the earth is in constant motion and so are the things on it.  


NCERT Solutions for Class 9 Science Chapter 9 Force and Laws of Motion

The Force and Laws of Motion chapter enhances one’s conceptual understanding of force and motion. It discusses the 3 laws of motion, namely the first, second, and third law of motion, and exposes students to balanced and unbalanced forces.  


NCERT Solutions for Class 9 Science Chapter 10 Gravitation

Newton had wondered why the apple fell from a tree. This led to the existence of gravitational force being discovered and discussed by him. This chapter will discuss the gravitational force in detail (its importance, mass, weight, free fall, etc.) and includes numericals based on it. Good practice will be required to ace the numerical questions. So buckle up and practice well. 


NCERT Solutions for Class 9 Science Chapter 11 Work and Energy

Different examples, activities, and numericals are utilized to define the concept of work in this chapter. Energy and its forms are explained with examples for better understanding. .

CBSE Class 9 Science Examination – Preparation Tips

  • NCERT Solutions for Class 9 Science include many important questions that are a part of the Class 9 CBSE Exam Syllabus. Learn and understand all the concepts well. Science is something you can’t understand by rote learning. It’s the application of knowledge and understanding.
  • Practice diagrams well. Do not draw diagrams with a pen. Do it with a pencil.
  • Answer what you know first. Do not waste too much time on one question.
  • Practise numerical questions well. 
  • Solve model question papers and previous years’ question papers to test yourself and to get an idea about the type of questions that will come in the exam. 
  • Physics questions will mostly be conceptual and numerical. Newton’s laws of motion and their application, diagrams like electric circuit diagram, lines of a magnetic field around a solenoid and bar magnet, image formation by lenses and mirrors, AC and DC generators, glass prism, the human eye, image formation for corrected and defected vision are some of the important  chapters you need to do it thoroughly. Numericals on lens and mirror and the series and parallel combination of resistances are frequently asked to test your skills. 
  • Chemistry  should be prepared well by understanding the modern periodic table with electronic configuration properly, memorising the elements placed in the Periodic table’s first and last two groups, and applications of acids, basis, and salt in day-to-day life. Learn  how to balance chemical equations and  take proper notes  on reactions involving conversion compounds which will act as revision notes during exams. It is advisable to focus on carbon compounds and the nomenclature containing functional groups.
  • Biology can be aced by revising complex terminologies regularly, preparing Mendel’s experiments, understanding traits inheritance, functions of reproductive organs in humans, and the process of reproduction in plants. Diagrams  of different parts of a flower, respiratory system, representation of reflex action, human brain, male and female reproductive organs, etc. can be practiced for better results.
