# NCERT Solutions for Class 6 Science Chapter 10 - Motion and Measurement of Distances

NCERT solutions for class 6 science chapter 10 Motion and Measurement of DistancesMiddle school starts with class 6 where science is an important and scoring subject. Chapters related to motion are studied in higher classes too. This is where solutions of NCERT class 6 science chapter 10 motion and measurement of distances are useful. The CBSE NCERT solutions for class 6 science chapter 10 motion and measurement of distances explains 10 questions. With the help of these questions, students can understand how much they have grasped from the chapter. NCERT solutions for class 6 science chapter 10 motion and measurement of distances explains a few numerical problems based on the conversion of the unit of length. That is kilometres to meter and vice-versa, centimetre to the millimetre, meter to the centimetre etc. A tool like solutions of NCERT helps in preparation of exams. The chapter motion and measurement give an idea about different modes of transport, standard units of measurement and types of motion.

## Here are the important topics of NCERT Class 6 Science Chapter 10

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

## NCERT solutions for class 6 science chapter 10 motion and measurement of distances exercise:

Two examples of modes of transport used on land are cars and bicycles.

Two examples of modes of transport used on the water are submarines and ships.

Two examples of modes of transport used in the air are aeroplanes and helicopters.

## 2 (i). Fill in the blanks: One metre is ______________ cm

One metre is 100 cm.

2 (ii). Fill in the blanks:

Five kilometre is ______________ m.

Five kilometres is 5000 m.

$\\1 km = 1000 m\\ 5 km = 5 \times 1 km\\ 5 km = 5 \times 1000 m\\ 5 km = 5000 m$

2 (iii). Fill in the blanks:

Motion of a child on a swing is ______________.

The motion of a child on a swing is periodic.

2 (iv). Fill in the blanks:

Motion of the needle of a sewing machine is ______________.

Motion of the needle of a sewing machine is periodic.

2 (v). Fill in the blanks:

Motion of wheel of a bicycle is_____________.

The motion of the wheel of a bicycle is circular.

Footsteps differ from person to person. So we cannot fix it as a standard unit for measurement of length.

$\\1\ cm = 10 \ mm. \\1\ m = 100\ cm = 100\times 10\ m=1000\ mm \\1\ km = 1000\ m = 1000\times 1000\ mm= 1000000\ mm$

Therefore 1 mm < 1 cm < 1 m < 1 km.

$\\1\ m = 100\ cm \\1.65\ m = 1.65\times 100\ cm = 165\ cm \\1\ cm = 10\ mm \\165\ cm = 165\times 10\ mm = 1650\ mm$

The height of the person in centimetres is 165 cm and in millimetre is 1650 mm.

$\\1\ km = 1000\ m \\1\ m = \frac{1}{1000}\ km = 0.001\ km \\3250\ m\ =3250\times 0.001\ km = 3.25\ km$

The distance between Radha's home and her school is 3.25 km

Reading of the scale at one end = 3.0 cm.

Reading of the scale at the other end = 33.1 cm.

Length of the needle = 33.1 cm - 3.0 cm = 30.1 cm

Similarities between the motion of a bicycle and a ceiling fan that has been switched on are:

(i) The blades of the fan and the wheels of the bicycle are in a circular motion.

(ii) The blades of the fan and spokes of the wheels of the bicycle are fixed at a certain point.

Differences between the motion of a bicycle and a ceiling fan that has been switched on are:

(i) The bicycle is in linear motion, unlike the fan.

(ii) The motion of the blades of the fan is periodic whereas that of the cycle is rectilinear.

A measuring tape made of elastic material would be stretchable and while measuring the distance between two points it might get stretched and would give an incorrect measurement.

Two examples of periodic motion are:

(i) The needle of a sewing machine.

(ii) The blades of a fan which is switched on.

## Important conversions of the unit of length:

The following conversions are used to solve the numerical in the NCERT solutions for class 6 science chapter 10 motion and measurement of distances.

• 1 Km = 1000 m which means, multiply with 1000 to convert Km to m and divide with 1000 to convert from m to Km
• 1m = 100 cm implies that multiply with 100 to convert m to cm and divide with 100 to convert from cm to m
• 1 cm = 10 mm shows that multiply with 10 to change the unit from cm to mm and divide with 10 to change from mm to cm

Out of 10 questions discussed in the CBSE NCERT solutions for class 6 science chapter 10 motion and measurement of distances 5 are based on the above-mentioned concepts.
