### CBSE Class 11 Physics Chapter 3 Motion in Straight Line NCERT Solutions

NCERT Solutions for Class 11 Physics Chapter 3 deals with Motion in Straight Line. First of all, motion refers to a change in position of an object. Furthermore, this change is with respect to the surroundings of the object. Also, this change takes place in a given interval of time. Motion is certainly common to everything in the Universe. Most noteworthy, this chapter is a part of kinetics. The chapter contains information about rectilinear motion here. There is also information here about reference point and frame of reference. The chapter also deals with average velocity and speed. There is also a discussion of instantaneous velocity and speed. Acceleration is also a part of this chapter.

### Subtopics covered under NCERT Solutions for Class 11 Physics Chapter 3

• 3.1 Introduction
• 3.2 Position, path length, and displacement
• 3.3 Average velocity and average speed
• 3.4 Instantaneous velocity and speed
• 3.5 Acceleration
• 3.6 Kinematic equations for uniformly accelerated motion
• 3.7 Relative velocity

### NCERT Solutions for Class 11 Physics Chapter 3

Motion is a topic that has extreme usage. In every field of science, motion is essential. Furthermore, the chapter is vital for automobiles companies. This is because acceleration, speed, and velocity are very important in automobiles. Also, engineers consistently make use of motion-related concepts. This chapter will certainly prepare students in astronomy. This is due to the study of motion of heavenly bodies and other issues in astronomy.

Below is a brief discussion of the sub-units of the chapter:

#### 3.2 Position, path length, and displacement â€“

This sub-unit discusses three aspects of motion. Above all, these aspects are Position, path length, and displacement.

#### 3.3 Average velocity and average speed â€“

Average velocity changes in displacement divided by the time intervals. Furthermore, these time intervals are those in which the displacement occurs. In contrast, average speed describes the rate of motion over the actual path.

#### 3.4 Instantaneous velocity and speed â€“

The velocity of an instant is the limit of the average velocity as the time interval gets infinitely small. This is clearly in contrast to instantaneous speed. Instantaneous speed refers to the magnitude of velocity.

#### 3.5 Acceleration â€“

This refers to the rate of change of velocity of an object with respect to time.

#### 3.6 Kinematic equations for uniformly accelerated motion â€“

This part has simple equations. Most noteworthy, these equations relate various aspects of motion.

#### 3.7 Relative velocity â€“

This is an aspect of velocity. Above all, this is the velocity of an object in the rest frame of another object.
