What will you learn in CBSE Class 11 Physics Chapter 3 Motion in A Straight Line?
NCERT Solutions for Physics for CBSE class 11 explain the concepts of linear motion straightforwardly so that students can better understand them. The chapter starts with a brief introduction to motion and goes on to talk about various other related aspects, such as position, path length, displacement, speed, and velocity.
The solutions also have exercise questions. And teachers recommend to the students to answer them so that they get enough practice.
The chapter has seven different sections, including the introduction. While the second section covers path length displacement and position, the third section tells students about average speed and velocity. Similarly, the fourth section talks about instantaneous speed and velocity, while section five is all about the concept of ‘acceleration.’
Likewise, the last two sections of the chapter cover equations in kinematics related to acceleration and relative velocity, respectively.
Besides this, the chapter also gives the graphical representation of linear motion and asks students to calculate the speed, distance, velocity, and acceleration. Other concepts like the difference between the total distance covered and the magnitude of displacement also find their places in the chapter.
Subtopics of Class 11 Physics Chapter 3 Motion in a Straight Line | Chapters Under Kinematics Class 11 NCERT
- Introduction

Important Formulae and Theorems
The formulae used throughout the chapter are in line with the concepts discussed, such as velocity, speed, distance, and acceleration. However, some are more important than others, and so, we have given them in the following section.
For instance, to find the relative speed of an object, you can make use of the following formula.
Vc = VOE – VE
In the above formula,
VC is the speed of the object we must find.
VE is the speed of another object with respect to the speed of the object we must find.
VOE is the speed of the other object with respect to an observer.
Similarly, there is also one other formula to find the final velocity of a moving object, which is as follows.
V = u + at
In this formula,
‘V’ is the final velocity of the moving object.
‘u’ is the initial velocity of the moving object.
‘a’ is the acceleration.
‘t’ is the time taken.
NCERT solutions concisely explain different concepts related to linear motion. So, by going through them, students can become thorough with each concept in the chapter. Linear motion is one of the most fundamental concepts in Physics. Only by understanding it thoroughly can you be clear with other, more complex ideas.

What are the topics covered under Chapter 3 of NCERT Solutions for Class 11 Physics?
The topics covered under Chapter 3 of NCERT Solutions for Class 11 Physics are listed in the above article.
In Chapter 3 of NCERT Solutions for Class 11 Physics, what does acceleration mean?
The rate of change of velocity with respect to time is known as acceleration. Because it has both magnitude and direction, acceleration is a vector quantity. It is also known as the first derivative of velocity with respect to time or the second derivative of position with respect to time.
