FAQs on Measurement of Length and Motion Video Lecture - Science for Class 6

1. What is the standard unit of length in the metric system?
Ans. The standard unit of length in the metric system is the meter (m). Other smaller units include centimeters (cm) and millimeters (mm), while larger units include kilometers (km).
2. How do we measure length using a ruler?
Ans. To measure length using a ruler, place the edge of the object at the zero mark of the ruler. Then, read the measurement at the other end of the object. Ensure the ruler is aligned straight for an accurate reading.
3. What is the difference between distance and displacement?
Ans. Distance is the total path traveled by an object, regardless of direction, while displacement is the shortest straight line from the starting point to the endpoint, along with the direction. Displacement can be zero even if distance is not.
4. Why is it important to use standard units of measurement?
Ans. Using standard units of measurement is important because it ensures consistency and clarity in communication. It allows people to understand measurements accurately, regardless of their location or background.
5. What are some common tools used to measure length?
Ans. Common tools used to measure length include rulers, measuring tapes, meter sticks, and calipers. Each tool is used for specific types of measurements, whether for small objects or larger distances.
