NCERT Solutions for Class 11 Physics Chapter 4 Motion In a Plane

 

Let us start reading the preparation article Regarding CBSE 11 Class

NCERT Solutions for Class 11 Physics Chapter 4 Motion In a Plane: Consider the motion of an ant on a plane as shown in the figure.

The ant moves from the point a toe in the direction shown in the figure. We have to find out the displacement of the ant from the point a (0,0). From figure displacement ae=\sqrt{2}, this is an incomplete statement because we didn't specify the direction of displacement. Suppose the above figure is not available and if we specify the ant has a displacement of magnitude 1.414 from the origin, then there are n number of such possibilities.  So to specify the direction of displacement we have to use the concept of vectors. So to study the motion of an object in a plane or in space we must be aware of the basics of vector algebra. So NCERT Solutions for Class 11 Physics Chapter 4 Motion In a Plane starts with an introduction to vectors. The concept of vectors mentioned in the NCERT class 11 Physics chapter 4 Motion in a Plane is very important and we are going to use it in the entire Physics course.

The main topics of NCERT Solutions for Class 11 Physics Chapter 4 Motion In a Plane are mentioned below.

4.1 Introduction

4.2 Scalars And Vectors
