FAQs on Motion and Measurement of Distances Class 6 Worksheet Science Chapter 7

1. What is motion and measurement of distances?
Ans. Motion refers to the change in position of an object with respect to its surroundings. Measurement of distances is the process of determining the length between two points or objects using appropriate units of measurement.
2. Why is it important to study motion and measurement of distances?
Ans. It is important to study motion and measurement of distances as it helps us understand how objects move and interact with their surroundings. This knowledge is crucial in various fields such as physics, engineering, and navigation.
3. What are the different units used for measuring distances?
Ans. Distances can be measured using various units such as meters (m), centimeters (cm), kilometers (km), and miles (mi), depending on the magnitude of the distance being measured.
4. How do we measure distances accurately?
Ans. Distances can be measured accurately using tools such as rulers, measuring tapes, and measuring wheels. It is important to ensure that the measurement tool is properly aligned and that the starting and ending points are clearly marked.
5. How can we calculate the speed of an object in motion?
Ans. The speed of an object in motion can be calculated by dividing the distance traveled by the time taken. The formula for speed is: Speed = Distance/Time.
