Chapter 10 - Motion and Measurement of Distances

  1. A body is said to be at rest when the body/object remains stationary at its place and does not change its position.

  2. To go from one place to another, different modes of transport are used. In ancient days, people used the length of a foot, the width of a finger, as units of measurement. This led to lots of confusion and the need to develop a uniform system of measurement. The International System of Unit also called SI unit is accepted all over the world. The unit of length in SI unit is metre.

  3. Rectilinear motion is the motion of the body in a straight line.

  4. In a circular motion, a body moves in such a way that its distance from a fixed point remains the same.

  5. Periodic motion is the motion that repeats itself after some $T$ interval of time.

  6. Measurement of an object consists of: Its unit of measurement and the number of units that the object measures.

  7. Conventional Methods: They give approximate measurement.

    1. Handspan: It is the distance  between the tip of the thumb and little finger. 

    2. Cubit: Length taken from the tip of the middle finger and elbow.

    3. Arm length: Length taken from shoulder to the tip of the middle finger.

    4. Footstep: It is the distance covered in a step.

  8. Disadvantages: Differed from person to person and lacked precision.

  9. Why do we need standard units of measurement?

The conventional units such as hand span, foot, footstep, cubit etc. varied. They used to depend upon the size of an individual's hand, foot, and body parts, hence such units caused a lot more confusion in measurements.

  1. Standard Units of Measurement: These are the units for measuring any quantity completely and uniformly. Some standard units for measuring, length-metre, mass-kilogram, time-second.


    1. Symbols for standard units are written in small letters.

    2. Symbols are not written in the plural.

  3. Motion:  When the position of a body changes with the passage of time, the body is said to be in motion. 

Types Of Motion:

  1. Linear Motion: Linear motion is of two types:

    1. Straight line motion: When the object moves from one position to another along a straight line. For example: Group of ants moving in a straight line.

    2. Curvilinear Motion: When the object moves along curved lines. For example: a car travelling along a curved road.

  2. Random Motion: When a body starts moving from one position to another and changes its direction in an irregular manner, then the body is said to be in random motion. For example, Insects flying randomly in the garden.

    1. Circular Motion: When the object moves in a circular path in relation to its own axis or around a fixed centre. An object remains at the same distance from a fixed point which is the center of the path of the motion. Two types of circular motion:

    2. Revolution: Revolution: When the object moves around a fixed center. For example, Earth revolves around the sun in its orbit.

    3. Rotation: When the object moves in a circular path with respect to its own fixed axis. For example, the blades of a moving fan, windmill, etc. Rotation is bound to the central axis. And the extended parts attached to the rotating axis are in revolutionary motion.

    4. Vibratory Motion: When the object moves in to and fro very fast. For example, when strings of a guitar are plucked.

    5. Oscillatory motion: Object oscillates to and fro along the same path and with the constant speed. The time taken by an object to complete one oscillation is the same, irrespective of how many oscillations the object takes. For example, human heartbeat, a pendulum of a clock etc.

    6. Periodic motion: The body is said to be in periodic motion when it repeats at regular intervals of time. For example, the heartbeat of a person, the hands of a clock.

    7. Non-periodic Motion: The object is said to be under non-periodic motion when it does not repeat its motion at regular intervals of time.

    8. Mixed motion: When more than one type of motion occurs at the same time. For example, a cricket ball when bowled shows linear and spin motion as well.

    9. Resultant motion: The resultant motion is the motion that results in another kind of motion. For example, the wheels of a bicycle rotate about its axis which results in the linear motion of the bicycle on the road.

    10. Random motion: The motion irrespective of any sequence or direction is a random motion. For example, a buzzing bee, a football player on the field.

    11. Uniform Motion: The body is said to be in uniform motion when it covers equal distance in an equal interval of time. For example, the motion of the hand of a clock.

    12. Non-uniform Motion: The body is said to be non-uniform when it covers unequal distances in equal intervals of time. For example, the motion of a bus along a path.

FAQs on Motion and Measurement of Distances Class 6 Notes CBSE Science Chapter 10 (Free PDF Download)

Q1. What is the difference between non standard and standard measurements, according to Chapter 10 of Class 6 Science?

  • Non Standard Measurements - When an individual measures an object keeping into account the length of the arms, hands or fingers , this measurement is never reliable and accurate because the length of one’s hands, arms or fingers are different compared to the other individual. These methods therefore become the Non standard measurements. 

  • Standard Measurements - When the measurements are the same all over the world for the same object, then that is referred to as the standard measurements. 

The Revision Notes for Chapter 10 of Class 6 Science by Vedantu will help the student in attaining a better understanding of the concepts. They are available free of cost on the Vedantu website and the Vedantu app.

Q2. What are the different types of motions, according to Chapter 10 of Class 6 Science?

  • Rectilinear motion: This type of motion refers to the motion in a straight line. For example, the vehicles moving in a straight line on the road or the athletes running straight on the track.

  • Circular motion: Circular motion refers to the movement of any given object in a circular path along the circumference of the circle. For instance, if one ties a stope to a string and rotates it, the motion thus produced is the circular motion or the fan's rotation.

  • Periodic motion: When an object repeats its motion after a given time, it is termed the periodic motion. For instance, the motion produced by a pendulum.

Q3. What is the right procedure in the measurement of a length with a broken scale, according to Chapter 10 of Class 6 Science?

To measure the length of any given object precisely, the following steps are to be followed:

  • The first step involves the placement of the scale in contact with the given object.

  • While taking the measurements, starting from the zero mark is to be avoided.

  • For instance, the full mark on a scale, 1.0 rather than 1.7, is to be used.

  • The reading of one particular end is subtracted from the reading of the other end. For instance, if the reading at the starting, placed from the mark 1 cm, ends with the reading of 5.5 at the other end, the length of the object will be 5.5-1.0= 4.5

  • Another important point to be remembered while measuring an object is that the position of the reader’s eye also matters. Therefore the position of the eye should be exactly above the point where the measurement is to be taken.

Q4. Explain when there is a combination of two or more motions, according to Chapter 10 of Class 6 Science?

In some cases, it is seen that the object's motion might include the combination involving two or more motions. Some examples of it are as follows -

  • A rotating ball in motion on the ground makes it clear that because the ball is rotating, it follows a rotatory motion, but it is also moving in a straight line. Thus it can also be said to execute a rectilinear motion.

  • The motion of a vehicle on the road: the vehicle's wheels can be seen to perform the rotatory motion, but as the vehicle is moving in a straight line, it can also be said to perform the rectilinear motion. 

Q5. Is it important to read the activities that are given in Chapter 10 of the Class 6 Science book?

The Chapter 10 of Class 6 Science CBSE textbook provides different sections concerning the activity to the topic being taught. If practiced, these activities will help students understand and learn the concepts in a new and better light. These activities are extremely easy to follow and require everyday items for their function. Therefore, it is easy for students to use the items and practice them to have a fun experience and the learning process.
