1. Motion of the needle of a sewing machine is ______________.

Ans: Oscillatory motion

1. Motion of the wheel of a bicycle is______________.

Ans: Circular motion

1. Why can a pace or a footstep not be used as a standard unit of length?

Ans: A pace or a footstep cannot be used as a standard unit of length because the length of a footstep is different for different people. Since the size of the pace of different people is different, the same length measured by two people with their pace or footstep would be different. Also, a standard unit must not change with time and space, irrespective of the person doing the measurement. Thus we cannot use a pace or a footstep not be used as a standard unit of length.

1. Arrange the following lengths in their increasing magnitude: 1  metre, 1 centimetre, 1  kilometre, 1  millimetre.

Ans: It is known that millimetre (mm) is the smallest and kilometre (km) is the largest.

Also, 1 cm = 10 mm; 1m = 100cm; 1km=1000m.

Based on this, the arrangement observed is -  1mm<1cm<1m<1km

1. The height of a person is 1.65 m. Express it into cm and mm.

Ans: Given: Height =1.65m

It is know that,

• 1 cm = 10 mm

• 1m = 100 cm

• 1m = 100x10mm

• 1m = 1000mm

Now, first convert the given height in metres to centimetres (cm) and millimetres (mm).

• In centimetre - (1.65 x 100) cm = 165cm

• In millimetre - (1.65 x 1000) = 1650mm

Thus, the height of the person in cm is 165 cm and in mm is 1650 mm.

1. The distance between Radha's home and her school is  3250m. Express this distance into km.

Ans:

Given: Distance between Radha’s home and school =3250m

It is known that,

1km=1000m

1m= 1/1000 km

Now, converting m into km:

3250m = (1/1000 x 3250)km

3250 m =3.25km

Thus, the distance between Radha's home and her school in km is 3.25km

1. While measuring the length of a knitting needle, the reading of the scale at one end is 3.0cm and at the other end is 33.1cm. What is the length of the needle?

Ans: The length of the needle can be found by subtracting the readings at the two ends of the needle.

Hence, the length of the needle = 33.1 cm - 3cm = 30.1cm.

The length of the needle is 30.1 cm.

1. Write the similarities and differences between the motion of a bicycle and a ceiling fan that has been switched on.

Ans:

• Similarity – Both the motion of a bicycle, specifically its wheel, and that of a ceiling fan represent a circular motion, since both objects are moving about a circular path from a fixed point.

• Difference – For a bicycle, along with the circular motion of its wheels, it also exhibits translational motion, moving linearly or in a straight line. While the ceiling fan only shows circular motion.

1. Why can you not use an elastic measuring tape to measure distance? What would be some of the problems you would meet in telling someone about a distance you measured with such a tape?

Ans:

• The main property of an elastic material is its elasticity, where it can stretch when pulled and deform based on the force used during the pull and contraction.

• Since elastic measuring tapes are stretchable, the length being measured can show different readings depending on the applied force during the pulling. This means that the length of the tape will change each time during stretching.

• Thus while measuring the distance with an elastic measuring tape we will get different values for the same distance being measured.

• Also if the same distance is being measured by two people using the elastic tape while applying different forces, they would get different measurements.

1. Give two examples of periodic motion.

Ans: Periodic motion is the motion that repeats itself after regular intervals of time.

Examples of periodic motion – Swinging pendulum, Motion of a rocking chair, Motion of a swing, Hands of a clock, Revolution of Earth around Sun and Moon around Earth.

### Important Topics Covered Under Class 6 Science Chapter 10

The important topics of Motion and Measurement of Distances are given below which are included in the syllabus.

 Section Topic Name 10 Motion and Measurement of Distances. 10.1 Story of Transport. 10.2 How Wide is this Desk? 10.3 Some Measurements. 10.4 Standard Units of Measurements. 10.5 Correct Measurement of Length. 10.6 Measuring the Length of a Curved Line. 10.7 Moving Things Around Us. 10.8 Types of Motion.

### Important Points to Remember

• Standard measures are those measures that are the same all over the world.

• The 12th general conference on weight and measures in October 1960 adopted the International system of units. “The System International Units” is the set of units that were established to maintain uniformity all over the world.

• The standard unit of length is Metre.

• One metre is divided into 100 equal divisions, called centimetres. Further, one centimetre has ten equal divisions, called millimetres. Hence

• 1 millimetre = 100 centimetres

• 1 centimetre = 10 millimetres

• Kilometre is a unit of length that is used for measuring large distances for which a metre is not a convenient unit. We define a larger used for measurement for long distances.

1 km = 1000 m.

### 10.1 Story of Transport

Transport was a problem for people in the early days. Since they did not have any vehicle, they used to travel on foot. The discovery of wheels brought about a revolution in transport facilities. They found out that they can use wheels to travel long distances in shorter periods. As a result, they could do more work in less time.

On the water, wheels were not a proper option. People found out that dead wooden planks can float on water. They started to make vessels from wooden planks and made boats. People after that started to travel on boats on the water. Motors were then added to these wheel-driven transports to increase the speed. A detailed explanation of how the transport facilities emerged is discussed in NCERT solutions for Class 6 Science Chapter 10.

### 10.2 How Far have you Travelled? How Wide is this Desk?

NCERT solutions Class 6 Science Chapter 10 speaks about the importance of distance.

Before we start travelling, we need to know how much we need to travel. If the travel is for a short distance, we can cover it on foot. However, for long-distance travel, we need to use a car. For measuring the distance, we need to express it in terms of length. The measurement is done in the same way as that of measuring the width of a desk. We can use a Gilli and a danda, strings or rulers to measure the width.

However, for measuring long distances, we use larger scales. Another way of measuring the distance travelled is by multiplying the wheel's circumference to the number of rotations the wheel has to perform to cover the entire distance. You will learn more about measuring distance in NCERT Class 6 Science Chapter 10.

### 10.3 Some Measurements

Measurement is the means of comparing an unknown quantity with the features of a known quantity. The comparison is depicted in two parts- one part is the number, and the other part is the unit. There are defined units for different entities followed across the world. These measurements do not change from person to person. If you want to know more about measurements as discussed in Motion and Measurement of Distances Class 6, download NCERT solutions for Class 6th Science Chapter 10 PDF from the Vedantu website.

### 10.4 Standard Units of Measurement

The standard units of measurements are followed across all the countries. However, countries may have regional units as well. For example, in ancient India, people used to measure small distances with their fingers. However, the units of length are followed universally in terms of metre. Similarly, there are other units for other measurable quantities like gram for weight, degrees for temperature, Pascals for pressure etc. You will get an entire list of all the measurement units in NCERT solutions for Class 6 Science Chapter 10.

### 10.5 Correct Measurement of Length

Length is universally measured in terms of metre. However, for smaller lengths, a centimetre is used, and for larger lengths, kilometres and miles are used. The correct way to measure the length is to measure it in a straight line. The correct way to measure length is mentioned in NCERT solutions for Class 6th Science Chapter 10. Use a ruler to measure length. Make sure that you keep the ruler in the right position in front of your eye. The 0 marks should coincide with the end of the object. If the ruler's ends are broken that the 0 mark is faulty, you can start measuring from any marked point. You need to subtract your beginning point from the final reading to measure the object's correct length. A detailed step-by-step protocol is discussed in NCERT solutions of Class 6 Science Chapter 10.

### 10.6 Measuring the Length of a Curved Line

In some cases, the object might not have a straight line edge. It can have a curved side or side of any shape. To measure the curved line's exact length, NCERT Class 6 Science Chapter 10 solutions will help you in the process. For this purpose, you will need a string. Place the string along with the curvature of the line. Mark the starting and the endpoint of the line on the string. Then measure the length between these two points with the help of a ruler. The detailed process is discussed in NCERT solutions for Class 6 Science Chapter 10 Motion and Measurement of Distances.

### 10.7 Moving Things Around Us

If you look around, there are different things at rest and in motion around us. For example, a table is at rest, while a fly is in motion. You can make a list of different objects and monitor their state of rest or motion. Therefore, you can define motion in terms of a change in the position of an object. If you want to know more details on this topic, study NCERT Class 6 Science Chapter 10 solutions. Download the PDF version of this solution on Motion and Measurement of Distances Class 6.

### 10.8 Types of Motion

Class 6 Science Chapter 10 presents different types of motion. Different bodies around you depict these motions, for example, a train moves in a straight line. Soldiers march in a straight line. The ceiling fan exhibits circular motion. Swings or pendulum exhibits oscillating motion. Musical instruments show vibrational motion. NCERT solution for Class 6 Science Chapter 10 has the right approach in explaining these motions. You can download the Motion and Measurement of Distances Class 6 PDF from the Vedantu website.
