Measurement is a fundamental aspect of science and daily life, helping us understand and quantify the world around us. In Chapter 5 Measurement of Length and Motion, we explore the basic concepts of measuring length and the different types of motion objects can exhibit. Chapter 5 introduces the International System of Units (SI units), with a focus on the metre as the standard unit for length. It also gives insights into how we measure distances and the various forms of motion that objects can undergo.

Glance on Class 6 Science (Curiosity) Chapter 5 Measurement of Length and Motion

  1. SI Units for Measurement:

  • The standard unit of length is the metre (m).

  • Conversion factors: 1 kilometre (km) = 1000 metres (m), 1 metre (m) = 100 centimetres (cm), and 1 centimetre (cm) = 10 millimetres (mm).


  1. Reference Point: A reference point is a fixed point used to measure distance from a field object or point.


  1. Types of Motion:

  • Linear Motion: Motion along a straight path.

  • Circular Motion: Motion along a circular path.

  • Oscillatory Motion: Motion that repeats in a to-and-fro manner.


  1. Practical Example: Deepa, a young girl, experiences different methods of measuring length when buying clothes for a new uniform. The chapter highlights her experience of using a metal rod and a flexible measuring tape.

Question 1. Some lengths are given in Column I of the following Table. Some units are given in Column II. Match the lengths with the units suitable for measuring those lengths.


Column


Answer:

Column I

Column II

Distance between Delhi and Lucknow

kilometre

Thickness of a coin

millimetre

Length of an eraser

centimetre

Length of school ground

metre


Question 2. Read the following statements and mark True (T) or False (F) against each.
(i) The motion of a car moving on a straight road is an example of linear motion.
Answer: True


(ii) Any object that is changing its position concerning a reference point with time is said to be in motion.
Answer: True


(iii) 1 km = 100 cm
Answer: False


Question 3. Which of the following is not a standard unit of measuring length?
(i) millimetre
(ii) centimetre
(iii) kilometre
(iv) handspan
Answer: (iv) handspan


Question 4. Search for the different scales or measuring tapes at your home and school. Find out the smallest value that can be measured using each of these scales. Record your observations in a tabular form.

Answer:


Type of Scale, Tape, Device

Smallest Value of Measurement

15 cm Scale

1 mm

Flexible Tape

1 mm, 1 inch

Long Tape Roll

1 cm, 1 inch

Vernier Calliper (from School Lab)

0.1 mm

Screw Gauge (from School Lab)

0.01 mm


Question 5. Suppose the distance between your school and home is 1.5 km. Express it in metres.
Ans.
∵ 1 km = 1000 metres
∴ 1.5 km = 1.5 × 1000
= 1500 metres


Question 6. Take a tumbler or a bottle. Measure the length of the curved part of the base of the glass or bottle and record it.
Answer: Hint: Use a flexible measuring tape or a piece of string to measure the length of the curved part of the base of the tumbler, then measure the string against a ruler.


Question 7. Measure the height of your friend and express it.
(i) metres
(ii) centimetres and
(iii) millimetres.
Answer:
Hint: Measure the height using a metre scale and express it in:

  • Metres (e.g., 1.4 m)

  • Centimetres (e.g., 140 cm)

  • Millimetres (e.g., 1400 mm)


Question 8. You are given a coin. Estimate how many coins are required to be placed one after the other lengthwise, without leaving any gap between them, to cover the whole length of the chosen side of a notebook. Verify your estimate by measuring the same side of the notebook and the size of the coin using a 15-cm scale.


Book


Answer: Hint: Measure the diameter of the coin and the length of the notebook. Divide the length of the notebook by the diameter of the coin to estimate the number of coins required. Say the diameter of the coin is 2 cm and the length of the notebook is 18 cm. Then \(\frac{18}{2}\) = 9 coins can be placed side to side along the length of the notebook. Verify by placing the coins end-to-end and measuring again.


Question 9. Give two examples each for linear, circular, and oscillatory motion.
Answer:

  • Linear motion: A car moving on a straight road, an eraser dropping straight down.

  • Circular motion: A merry-go-round, the motion of a whirling stone tied to a thread.

  • Oscillatory motion: A swinging pendulum, the motion of a metal strip pressed and released.


Question 10. Observe different objects around you. It is easier to express the lengths of some objects in mm, some in cm, and some in m. Make a list of three objects in each category and enter them in the following Table.


Sizes of objects around us


Objects


Answer:
Classify objects by the convenience of measuring in mm, cm, and m:


Size

Objects

mm

The thickness of a coin, the thickness of a cardboard, and the diameter of a small screw

cm

The length of a pencil, the width of a book, and the height of a water bottle

m

The height of a room, the Width of a playground, and the height of a lamppost


Question 11. A roller coaster track is made in the shape shown in Fig. A ball starts from point A and escapes through point F. Identify the types of motion of the ball on the rollercoaster and corresponding portions of the track.


Roller Coaster Track


Roller Coaster Track

Answer: Portions of the track and corresponding types of motion:

  • A to B: Linear motion

  • B to C: Circular motion (loop)

  • C to D to E: Circular motion

  • E to F: Linear motion


Question 12. Tasneem wants to make a metre scale by herself. She considers the following materials for it – plywood, paper, cloth, stretchable rubber, and steel. Which of these should she not use and why?
Answer: Tasneem should not use stretchable rubber because it can change length when stretched, leading to inaccurate measurements. Plywood, cloth, paper, and steel are more suitable as they maintain consistent lengths.


Question 13. Think, design, and develop a card game on conversion of units of length to play with your friends.
Answer: Create cards with different lengths and corresponding units (mm, cm, m, km). Each card can have a length in one unit and players must match it to its equivalent in another unit. For example, a card with “100 cm” would match with “1 m”.
