### Introduction

In the first section, you will be introduced to some concepts that are related to motion in a plane, such as concepts of position, displacement, velocity, and acceleration. Explanations relating to these concepts are included in the ch 4 Physics Class 11 NCERT Solutions.

### Scalars and Vectors

In thesection, students will gain basic understanding of scalars and vectors. Topics that are included in this section are like the difference between scalars and vectors, directions associated with scalars and vectors, definitions, displacement vectors, parallelogram law of addition, triangle law of addition, the magnitude of displacement and some other topics. Solutions to all these topics can be found in Motion in a Plane Class 11 NCERT Solutions.

### Multiplication of Vectors by Real Numbers

At this point of this chapter, students will learn how to derive an equation by using magnitudes and different formulas. They will also learn to multiply the vectors by using the real numbers.

### Addition and Subtraction of Vectors - Graphical Method

In this section, you will learn about the triangle law, parallelogram law of addition and its definitions. You will gain knowledge on formulas of the head-to-tail method, triangle method of vector addition, commutative laws, null vectors and subtraction of vectors in this section.

### Resolution of Vectors

With the help of this section, you will learn about the resolution of vectors and its implementation in a straight line. Getting an equation by using real numbers will be very easy after learning the concepts of this section.

### Vector Addition - Analytical Method

In this section, a student can learn to add vector numbers by an analytical method along with a graphical method.

### Motion in a Plane

In this section, you will learn about velocity, acceleration, finding out averages, and then finally finding out the motion in a plane.

### Motion in a Plane with Constant Acceleration

At this point of this chapter, you will learn how motion in a plane can be treated as two different simultaneous one-dimensional motions, both of which have a constant acceleration in two different perpendicular directions.

### Relative Velocity in Three Dimension

In this section, a student will learn to find out three-dimensional or 3-D motion in a plane by using relative velocity.

### Projectile Motion

This section will help you in gaining knowledge of the concepts of projectile motion.

### Uniform Circular Motion

This section gives a basic understanding of uniform circular motion.
