## Summary of NCERT Solutions for Class 11 Physics Chapter 4 – Motion in a Plane

NCERT Solutions for Class 11 Chapter 4 Motion in a Plane encompasses various important concepts from CBSE as well as entrance exams like JEE and NEET. It is important to study the chapter in detail in order to ensure that you cover all the concepts. Here are some important topics of the chapter that you need to keep in mind.

Scalars and Vectors

Here, students will learn the various applications of Scalars and Vectors and the laws that are associated with it. Various concepts such as Displacement Vectors, Different Laws of Addition, Magnitude of Vectors, etc., are taught in this part of the chapter. Quantities that can be described by a single number are known as scalar quantities. Some examples are time, mass, etc. Quantities that need magnitude and direction to describe a situation in full are referred to as vectors.

### Multiplication of Vectors by Real Numbers

Multiplication of Vectors can be of two types- Scalar Multiplication and Vector Multiplication. Multiplication of Vectors is done to assess the magnitude of vectors after multiplication.

Addition of Vectors is done to find the resultant of vectors acting on a body. It is important to note that vectors can be added geometrically;

Parallel Vectors

When two vectors have the same direction, they are known as parallel vectors. When a vector is multiplied to a scalar, the new vector is parallel to the original vector that is formed.

### Triangle’s Law of Vector Addition and Law of Parallelogram of Vectors

The addition of Vectors is understood with the help of both these laws. You’ll get an in-depth understanding of the application of both these laws in this section of the chapter;

Motion in a Plane

Various concepts related to motion in a plane will be brought to limelight in this section. With the help of these concepts, you’ll be able to understand how to determine the motion on a plane.
