Science students have a tough time changing their approach when shifting between classes. The biggest change takes place during the 7th standard for the increasing syllabus. Many new topics such as the Motion and Time Class 7 unit come into the fold.
This raises a lot of doubts for students who are slow to accept the changing days. Hence, our idea is to give them a brief walk through the chapter we mention above. As motion and time are 2 important pillars of modern scientific work, the act is necessary too.
Meanwhile, the unit also introduces the concept of numerical questions into the mix. This allows the students to better understand and appreciate the relation of time with other quantities. Moreover, the types of motion and other similar information help in getting a better grip too.

Motion and Time Topics
The first question coming to the front view in this chapter is the topic of motion. It takes a little awareness to understand the interesting nature of relating such quantities. As you move ahead, the involvement of time in deciding major equations becomes more evident.
The Motion and Time Class 7 chapter shows what it means to be in motion. When you say that a body will go from one position or state to another in x time, that state is motion. Hence, anything in the world which does not have a fixed nature or coordinate is under motion.
In other words, motion makes an object change with time in respect to its surroundings. Hence, it is also clear that for judging motion, the awareness of surroundings is important. This gives us a reference to judge the initial position of someone or the state of something.
Several quantities help in deciding the nature and status of motion. Meanwhile, these quantities will further qualify into 2 groups depending on their nature:
The reference of time is always as a basic quantity to determine a series of events within a frame. Hence, time usually categorizes into 3 different forms when talking about relativity:
The chapter focuses on the two basic quantities and how they relate to each other. A large number of questions from this category are available in the NCERT syllabus for young students.
Subtopics of Motion and Time Class 7
The chapter has a lot of subtopics to cover all the points for helping you out. One of the basic subtopics you will find in the motion and time class 7 unit is the types of motion.
Types of Motion
The content of the chapter explains how motion categorizes into different types over time. As a part of the syllabus, a lot of basic examples are present for an explanation. Depending on the nature of the movement, motion divides itself into:
- Straight Line Motion is when something moves from one place to another following a straight path. This is the most common category of movement or motion the mind will experience in daily life.
- Oscillating Motion refers to the type of motion a person sees in a pendulum. In this category, the object or body moves towards and away from a particular point.
- Reciprocating Motion is when a body undergoes when it moves in a straight path but to and from.
- Circular Motion comes to mind when a body traces an imaginary path similar to a circle. Hence, the start and endpoints of this whole movement will be the same.
Numerical on Time
A variety of numerical questions in the chapter are present on the topic of time. This contains a set of questions to calculate the distance and relate it with time. Hence, the concept of speed also comes into play while relating these terms.
The unit also uses the graph system to describe the relation between distance and time changes. For example, the straight-line graph comes when a body moves steadily with respect to time. Meanwhile, a 0 distance/time plot showing a body that has no motion behind itself.
Basic Formulas Useful in the Unit
A few formulas will come in handy when you are solving these questions from the 13th chapter. Hence, we advise you to focus on these topics with additional interest for a solid base.
|Time||Distance x Speed|
|Time||Km/hr. or m/sec|
|Distance||Km and meter|
Through these relations, the chapter gives you a total of 13 questions. Hence, a combination of these will help you for moving ahead with a clear understanding.
Other Topics in the Textbook
As we already mention to you, Class 7 presents a big challenge for science students. Hence, the syllabus respects the fact and presents a slow changeover from the typical concepts. Including the chapter of motion and time class 7, the book has a few other interesting ones.
We list some of the important ones that will help you towards an interesting time during studying.
- Plant Nutrition (Chapter 1 in the book)
- Animal Nutrition (Chapter 2 in the book)
- Fiber to Fabric (Chapter 3 in the book)
- Heat (Chapter 4 in the book)
- Wind, storms, cyclones (Chapter 8 in the book)
- Soil (Chapter 9 in the book)
- Electric Current (Chapter 14 in the book)
- Light (chapter 15 in the book)
Including these chapters, a total of 18 chapters are present in the whole book. Hence, the syllabus uniformly covers many topics to prepare you for the final test.
Importance of NCERT solutions
The book covers a wide variety of questions that will cover all the topics completely. Hence, going through these questions will give the important preparation for the final exams. Meanwhile, other books than the normal syllabus textbook are present in the market too.
These books cover the topics in a more wholesome manner. But in the end, the questions are mostly from the NCERT syllabus that you face.
In addition to the typical questions, the syllabus also has objective types. A number of these are present in the Olympiads you face throughout the year. The pattern also has one-word-type questions that help in concept building.
CBSE has this introduction of objectives in recent years to use a more complete approach. For higher classes, these questions also appear in several competitive exams across the year.
NCERT Books and Chapters
By clearing the concepts of all units and numerical, all doubts are easily dealt with. Many options are present in the market to find the complete solutions for these units. NCERT also encourages its students to use the booklets through their official link at decent rates.
The idea is always to make the educational facilities available across the country. Hence, these books are also available through government schemes for special kids. This also covers the NCERT mission of “available for all” education throughout the country.
