Important Topics for Lakhmir Singh Physics Class 9 Solutions Motion (Chapter 1)


If an object’s position changes with time, it is known as motion. It is basically described in the terms of distance moved or the displacement. Motion is of 2 types – Uniform motion and Non-uniform motion depending on the velocity, whether the velocity is constant or is changing.


The distance covered per unit time is known as the speed of the object.


When we move something from its place or position, this action of moving the object is known as the displacement.


The displacement which occurs per unit time is known as the velocity.


When 2 points are taken, the length between these 2 points is called the distance.

Summary of the Chapter 

In Chapter 1, the concept of motion is explained. Everything at some points shows movement and thus, Chapter 1 – ‘Motion’ is explained in detail. Motion is all about the change in position of an object. 

But motion is of 2 types- Uniform motion and Non-Uniform motion. The motion is said to be Uniform when a body travels an equal distance in equal interval of time whereas the motion is said to be Non-Uniform when a body travels the unequal distance in the same interval of time. Moreover, the concept of Speed and Velocity is also explained in the Chapter. 

The solutions given by Instasolv makes the concepts easy and understandable by the students. The solutions help in increasing the knowledge of students on a specific topic and subject. Hence, this pattern helps students so that they can score more marks in the subject.  

Exercise-Wise Discussion for Lakhmir Singh Physics Class 9 Solutions Chapter 1

There are in total of 10 exercises in Lakhmir Singh Physics Class 9 Solutions Motion (Chapter 1). All the questions are based on the latest exam pattern. 

Exercise 1

This exercise set tests your understanding of displacement and distance. The logical solutions to all the questions in this exercise will allow you to understand the basics of the concept. This exercise has around 7 questions.  This exercise set has short question answers. 

Exercise 2

This set of exercises has around 20 questions. This section has questions based on speed, distance, displacement, acceleration, types of motion, etc. Lakhmir Singh and Manjit Kaur solutions class 9 give you the solutions to all the questions so that you can understand everything in detail. 

Exercise 3 (Page  21)

To understand and solve this exercise that consists of 14 questions, it is essential for you to have knowledge of all the relevant formulas so that you can easily solve numerical problems. These numerical are on different topics like speed, distance, acceleration, etc. 

Also, you will be checked on a uniform and non-uniform acceleration. Along with this, you need to know about retardation or negative acceleration. Thus, it is essential to keep the concepts clear so that you can solve the questions. 

Exercise 4 (Page 22)

This exercise set has 6 numerical questions on different topics of the Chapter. If you would have understood the concept well, then you will easily solve the questions. These exercises check your clarity if you are able to solve numerical on velocity, the average time taken or acceleration. 

Exercise 5 (Page 39)

This exercise contains 10 short questions based on uniform and non-uniform motion along with the basics of graphs. 

This exercise is a mixture of graphs and numerical questions. The questions are based on speed, distance, velocity, acceleration and another difficult topic – retardation. 

Exercise 6 (Page 40)

This exercise contains around six questions which test you in terms of graphs, types of motion, and some fill in the blanks. All you need is a better understanding of all the topics in the Chapter. 

Exercise 7 (Page 41)

This exercise set has around 21 questions which test you on a mixed basis. All the types of questions like the one-word answer, numerical, graphs, etc.  

Exercise 8 (Page 42)

This exercise has 6 questions in total which are entirely graph-based. It is necessary for you to understand how to solve numerical problems with graphs. Instasolv is going to help you in this matter. 

Exercise  9 (Page 43)

This is the last exercise of the Chapter and has only 4 questions in total. These questions are also numerical based on the topics retardation, acceleration, velocity, etc. 

All the exercise sets are focussed to see how much you have learned from the Chapter.
