NCERT Solutions for Class 6 Science Chapter 10- Motion and Measurement of Distances
The important topics covered under Motion and Measurement of Distances Class 6 are as follows:
- 10.1 – Story of Transport
- 10.2 – How Wide is This Desk?
- 10.3 – Some Measurements
- 10.4 – Standard Unit 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
Some important points to remember in this chapter are:
- Standard measures refer to those measures that are the same throughout the world.
- The 12th general conference on Weight and measures (that was held in October 1960) adopted the International system of units. The International System of Units is a set of units that were established to maintain uniformity of units throughout the world.
- A metre is the standard unit of length.
- One metre is divided into 100 equal divisions, called centimetres. Further, one centimetre has ten equal divisions of millimetres. Hence we may conclude that:
- 1 metre = 100 centimetres
- 1 centimetre = 10 millimetres
- A kilometre is another unit of length that is used for measuring distances that are so large that a metre cannot be a convenient unit for measuring such large distances. Thus, a larger scale of measurement for long distances is defined where 1 kilometre= 1000 metres.
10.1 Story of Transport
Transport was a problem for humans in early days. Because of the absence of vehicles, humans had to travel on foot. Later, the discovery of wheels brought a revolution in transportation. Humans found out that they can use wheels to travel long distances in a shorter time. As a result, they could do more work during the time left.
However, the wheels were not a proper mode of transportation on the water. People found out that dead wooden planks float on the water. So they started making vessels from wooden planks, which led to the creation of boats. After that, people started travelling through boats on the water.
10.2 How far have you travelled and how wide is this desk?
The NCERT Class 6 Science Chapter 10 discusses the importance of distance. Before we start travelling, we need to know how much distance has to be covered. If it is short-distance travel, it can be covered on foot. However, a vehicle is needed for long-distance travel.
To measure the distance, it should be expressed in terms of length. If we are measuring long distances, we need to use larger scales.
Another way to measure the distance travelled is by multiplying the circumference of the wheel to the number of rotations it has to perform to cover the entire distance.
10.3 Some Measurements
Measurement is a means for comparing an unknown quantity with the features of a known one. Such a comparison is usually depicted in two parts – number and its unit.
The units are defined for different entities, and it is followed worldwide. The measurements do not change from person to person.
10.4 Standard Units of Measurement
All the countries follow standard units of measurement. However, some countries have regional units also. For example, people used to measure small distances with their fingers in India. However, the standard units of length followed universally is metres. Similarly, there are different units for measurable quantities like degrees for temperature and grams for weight.
10.5 Correct Measurement of Length
As mentioned earlier, length is measured universally in terms of metres. However, for smaller lengths, the unit of centimetre is used and for larger lengths, kilometres and miles are used. The correct way for measuring length is to measure it in a straight line.
Chapter 10 mentions the correct way to measure length.
10.7 Moving Things Around Us
If you look around, you will notice that there are many things at rest and in motion around us. For example, a chair is at rest while a butterfly is in motion. You can make a list of such objects and monitor their state of rest or motion. Having done so, you will find out that you can define motion in terms of a change in the position of an object.
10.8 Types of Motion
This section of the solution explains to you the different types of motion. The different bodies around you depict these motions, for example, a train moves in a straight line, swings or pendulums exhibit oscillating motion, the ceiling fan exhibits circular motion, musical instruments show vibrational motion and so on. Chapter 10 explains all these motions in detail.
