Questions Covered in This Chapter
These NCERT Solutions answer all 48 questions of this chapter. The questions solved are:
- Are the tape and rod similar to the scale that the elder sister has in her geometry box? What did mother mean by char angula?
- Oh, the number of handspans is different for all of us. So, what can we say about the length of the table?
- But why should the number be different?
- Would it be convenient to use the unit metre to measure larger lengths, such as the length of a railway track between two cities, or to measure smaller lengths, such as the thickness of a page of a book?
- Suppose we all measure the length of the table again, but this time using a metre scale. Will our results still be different?
- What is the correct way to place the scale?
- What is the correct position of the eye while reading the scale?
- How to measure the length if the ends of the scale are broken?
- How do visually challenged students measure lengths?
- Select some objects around you, such as a comb, a pen, a pencil, and an eraser to measure their lengths. Measure their lengths one by one using a metre scale and note down the measurements in Table 5.2.
- Some of your friends in the class would have measured the length of the same objects. Compare the lengths measured by you with that of your friends. Are the measured lengths the same or slightly different? If not the same, discuss the possible reasons for the differences.
- Why are some length measuring devices made up of flexible materials?
- Anish and his parents fixed electric string lights on the arches of the verandah of their house, as shown in Fig. 5.7, for a celebration at home. How would they have measured the required length of string lights?
- Tasneem and Padma say that the garden would be closer, while Deepa and Anish feel that the school would be closer, Hardeep thinks that both would be almost at an equal distance. Who do you think is correct?
- Then, why are their observations different?
- What do such kilometre stones indicate? How could Padma conclude that she was getting closer to her destination?
- Does this mean that the position of Padma, with respect to the reference point, is changing with time? When does the position of an object change with respect to a reference point? Does it change when an object is moving?
- Look around and prepare a list of five objects that are in motion and five objects that are at rest. Record your observations in Table 5.3. Think about how you decided whether an object was in motion or at rest. Write your explanation (justification) in Table 5.3.
- Compare and analyse your justifications. How can one decide if an object is in motion or at rest?
- Suppose you are travelling on a ship which is moving at a constant speed along a straight line on a calm sea. Suppose there is no window on the ship. Is there any way that you can determine whether the ship is moving or is stationary?
- Take an eraser and drop it from a certain height. Observe its motion. Does it move along a straight line?
- When an orange drops from the tree, does it move in a straight line?
- Have you seen the Republic Day parade? Recall the march-past of students during the parade. Do they move on a straight-line path?
- When an object moves along a straight line, its motion is called linear motion. Identify such linear motion in your surroundings.
- But do things always move along a straight line? You might have enjoyed playing on swings and merry-go-rounds. Are these types of motion also linear motion?
- Tie an eraser (or a potato) to one end of a thread. Hold the other end of the thread with your hand and whirl it (Fig. 5.15). Observe its motion. Is the motion of the eraser the same as that of a merry-go-round?
- Tie an eraser (or a potato) to one end of a thread. Hang the eraser by holding the other end of the thread (Fig. 5.16). Keep your hand steady. Using the other hand, take the eraser slightly to one side and then release. Does it start moving to and fro? Is its motion similar to the motion of a swing?
- Take a thin metal strip of about 50 cm long. Hold its one end pressed to a table. You may use a few books or a brick to hold it (Fig. 5.17). Press the free end of the strip slightly and let it go. Observe the motion of this end of the strip. Does it move up and down?
- Look at the picture of a children’s park (Fig. 5.18) or visit a children’s park. Observe different kinds of motions. Classify them as linear, circular or oscillatory motion. List them in Table 5.4. Give your justification for why you put each in a certain category.
- Some lengths are given in Column I of Table 5.5. Some units are given in Column II. Match the lengths with the units suitable for measuring those lengths.
- 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. (ii) Any object which is changing its position with respect to a reference point with time is said to be in motion. (iii) 1 km = 100 cm
- Which of the following is not a standard unit of measuring length? (i) millimetre (ii) centimetre (iii) kilometre (iv) handspan
- 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.
- Suppose the distance between your school and home is 1.5 km. Express it in metres.
- Take a tumbler or a bottle. Measure the length of the curved part of the base of glass or bottle and record it.
- Measure the height of your friend and express it in (i) metres (ii) centimetres and (iii) millimetres.
- 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.
- Give two examples each for linear, circular and oscillatory motion.
- 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 Table 5.6.
- A rollercoaster track is made in the shape shown in Fig. 5.19. 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.
- 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?
- Think, design and develop a card game on conversion of units of length to play with your friends.
- Can you find the thickness of a single page of your notebook or textbook using a scale? Think of a way and write it. Carry out the activity and report your result.
- Collect fallen leaves from the same tree. Identify the name of the tree whose leaves you have taken. Measure length and breadth of all these leaves using a 15-cm scale, as shown in Fig. 5.20. Record your observations in the Table 5.7. Discuss why the leaves of the same tree vary in length and breadth.
- Discuss with elders in your community what units were used for measurement of length in the olden days. Also, using the internet, try to find out about the length scales found in excavations of archaeological sites in India.
- Create a maze using lines of 1 cm, 2 cm and their combination. Part of it has been made for you in Fig. 5.21. Now use your imagination and expand it to a size as big as you want.
- How tall am I? Stand along a wall and with the help of an adult, mark your height (Fig. 5.22). Repeat it every three months to maintain a height record for yourself and your siblings.
- Let us design a fun method for measuring the distance between two places by using a bicycle. Attach a flexible metal strip to the spoke of the front wheel in such a manner that it hits the frame of the bicycle holding the wheel, every time it crosses it and produces a sound (Fig. 5.23). Now ride the bicycle slowly and count the number of times in which sound occurred. … Try to find out about a ‘Jones Counter’ which is attached to a bicycle wheel and is used for measuring distances.
Chapter at a Glance
- A measurement always has two parts — a number and a unit . Saying “the table is 13 handspans long” means 13 is the number and handspan is the unit.
- Body-based units — handspan (balisht), angula, foot, cubit — differ from person to person, so the same table gave 13, 14 and “a little more than 13” to different children. That is why the world agreed on standard units .
- The system used today is the International System of Units (SI) . The SI unit of length is the metre (m) , and 1 km = 1000 m , 1 m = 100 cm , 1 cm = 10 mm (so 1 m = 1000 mm and 1 km = 1,00,000 cm).
- Using a scale correctly: keep it in contact with the object and along its length , keep the eye directly above the mark being read, and if the zero end is broken, use any full mark and subtract — for example 10.4 cm − 1.0 cm = 9.4 cm.
- A curved line is measured with a thread or a flexible measuring tape; the thread is then straightened along a metre scale.
- Position is always stated with respect to a reference point . An object is in motion if its position changes with time with respect to that point, otherwise it is at rest . Motion may be linear, circular or oscillatory ; circular and oscillatory motion are periodic .
