Class 9 is where the Science subject gets divided
into three categories; Physics, Chemistry, and Biology. Giving time to all
three subjects become important. There are so many books that are available in
the market that provide solutions for unsolved problems from the main
textbooks. Finding the right reference book is again important. These reference
books provide step-by-step explanations for all the problems and additional
problems are solved to make the concept clear for students.
One of the best reference books that are
available online is Lakhmir Singh
Solutions. Students
are fond of this book as the concepts are explained in simple language and
every explanation is supported by a solved example. Lakhmir Singh and Manjit
Kaur are the authors of this book.
Importance of NCERT Solutions
Physics is all about laws, theories, and
applications. This subject is also based on the basics of Mathematics concepts
as these concepts are used in solving problems. Also, among students, Physics
is considered to be one of the complicated subjects. NCERT solutions help
students in understanding these concepts where simple problems are used for
explaining them. There are solved problems with a stepwise explanation.
Class 9 Physics Chapters
Chapter 8: Motion
The chapter explains concepts such as what is
motion and terms that are related to motion such as acceleration, velocity,
speed, displacement, distance, and the relation between these terms. There are
graphs that are used in this chapter to explain a uniform and non-uniform
motion.
Chapter 9: Force and Laws of Motion
Sir Isaac Newton did not just explain
gravitational force but there concepts of Physics such as laws of motion and
how force impacts the motion of objects.
Chapter 10: Gravitation
This is the chapter which explains why an apple
fell downward and not in the opposite direction. Also, other topics such as
what is a universal law of gravitation and buoyant force.
Chapter 11: Work and Energy
Work and energy are the two concepts that are
related to each other and are explained with real-life examples.
Chapter 12: Sound
Ever wondered how sound travels through air or
through solids to reach our ears? The propagation of sound, the reflection of
sound, and their production is explained in chapter 12.
Class 9 Exam Preparation Tips
●
Definitions, theories, and laws
remain unchanged. So remembering them becomes easy with the help of examples.
●
Practice difficult questions to
understand the application of equations and formulas that are explained in
chapters.
●
Do not use calculators to solve
problems.
●
Make a list of all formulas and
equations chapter-wise.
●
Practice derivations and
understand the relationship between different equations.
