This topic introduces the concepts of motion, distances and displacements
Introduction to CBSE Class 6 Science Chapter "Motion and Measurement of Distances"
In “Motion and Measurement of Distances,” students explore the concept of motion, including different types such as rectilinear motion, circular motion, and periodic motion. The chapter begins by discussing the various modes of transport humans have used over time, highlighting the evolution from simple walking to the complex modes of transportation we use today.
It delves into the history of measurement, showcasing how distances were measured in the past using body parts, which varied from person to person, leading to the development of standard units of measurement. The chapter introduces the metric system, which includes units such as meters, centimeters, and kilometers, explaining their importance in providing accurate and consistent measurements.
Through engaging activities and experiments, students learn how to measure distances using a ruler or a measuring tape and understand the concept of the scale. The chapter emphasizes the necessity of measurement in various fields, such as construction, science experiments, and everyday life, making it clear how fundamental these concepts are to our understanding of the world.

Questions and Answers for CBSE Class 6 Science Chapter "Motion and Measurement of Distances"
- Q1: What is motion?
ANS: Motion is the change in position of an object with respect to time and its surroundings. - Q2: Why was there a need to develop standard units of measurement?
ANS: Standard units of measurement were developed to replace inconsistent methods and ensure accuracy and uniformity in measuring distances. - Q3: What are the three main types of motion described in the chapter?
ANS: The three main types of motion are rectilinear motion, circular motion, and periodic motion. - Q4: How did ancient people measure distances?
ANS: Ancient people measured distances using body parts like the length of a foot, the width of a finger, or the span of an arm, which led to varied measurements. - Q5: What is the significance of the metric system?
ANS: The metric system provides a standardized way of measuring based on units like meters, kilograms, and seconds, facilitating accurate and universal communication of measurements. - Q6: How do you measure the length of a curved line?
ANS: The length of a curved line can be measured using a string to trace the curve and then measuring the length of the string with a ruler or measuring tape. - Q7: Why is it important to learn about motion and measurement in science?
ANS: Learning about motion and measurement is crucial in science for understanding the physical world, conducting experiments, and applying scientific principles to solve real-world problems. - Q8: What is a scale in the context of measurement?
ANS: A scale is a ratio that gives the relationship between the measurements on a map, drawing, or model and the actual measurements of the physical space or object. - Q9: Can the method of measurement affect the outcome of an experiment?
ANS: Yes, the method of measurement can significantly affect the outcome of an experiment, as inaccurate measurements can lead to incorrect conclusions. - Q10: What role does measurement play in everyday life?
ANS: Measurement plays a vital role in everyday life, from cooking and construction to health care and transportation, ensuring tasks are performed accurately and efficiently.
