Fibre to Fabric (Part - 2) class 6

 Fibre to Fabric 

Q.6. Which of the two are stronger: natural fibres or synthetic fibres?

Ans. Synthetic fibres are more stronger than natural fibres.

Q.7. What type of soil and climate are good for growing cotton?

Ans. Cotton fibre comes from the cotton plants which are grown in the fields by the farmers. Cotton crop is usually grown at places having black soil and warm climate.

Q.8. Which part of cotton plant provides cotton and how?

Ans. Fruit of cotton plant provides cotton. The fruits of cotton plants (called cotton bolls) are of the size of lemons. After maturing, the cotton bolls burst open to produce cotton seeds covered with white, soft cotton fibres. It looks like a field covered with snow.

Q.9. What is ginning? How is it done?

Ans. From the cotton bolls, cotton is usually picked by hand. The cotton fibres picked from the fields have cotton seeds in them. Fibres are then separated from the seeds by combing. This process is called ginning of cotton. Ginning was traditionally done by hand. These days, machines are also used for ginning.

Q.10. Name some states in India where cotton is mainly grown.

Ans. In India, cotton is mainly grown in the states of Maharashtra, and parts of Andhra Pradesh, Madhya Pradesh and Gujarat.

Q.11. State the various uses of cotton fibre.

Ans.  Generally, Cotton fibres are used for

  • making clothes, dresses, etc.
  • for filling pillows, mattresses and quilts.
  • the wicks of oil lamps.
  • Dressing in hospitals/First-aid kit

Q.12. What are Flax fibres?

Ans. The flax fibres are obtained from the stem of flax plant. The cloth made of stem fibres of flax is called linen.

Linen is used for making bed-sheets, etc.

Q.13. What are Coconut fibres?

Ans. The fibre present on outer covering of coconut are called coconut fibres.

The common name of coconut fibres is ‘coir’.

The coconut fibres are used for making ropes and mats.

Q.14. Explain how, jute fibre is obtained from jute plants.

Ans. Jute fibre is obtained from the stem of the jute plant. It is cultivated during the rainy season. The jute plant is normally harvested when it is at flowering stage. The stems of the harvested plants are immersed in water for a few days.

The stems rot by the retting process and jute fibres are then separated from water by hand.

Q.15. What is Retting?

Ans. The stems of the harvested plants are immersed in water for a few days. The stems rot by the action of micro-organisms and moisture on plants and fibres are left behind, this is called ‘retting’. 

Retting softens the bond between the fibres and the inner core. These fibres are then separated from water by hand.

Q.16. State the uses of jute fibre.

Ans. Jute is a strong plant fibre. So, Jute fibre is used to make ropes and jute bags (or gunny bags) which are used as shopping bags as well as for storing food grains such as wheat, rice, etc.

Q.17. Name some states in India where jute is mainly grown.

Ans. In India, jute is mainly grown in West Bengal, Bihar and Assam.

FRICTION Q.1. What is force? Write few of its characteristics. Ans.1.  A push or a pull on an object is called a force.                      Force is a vector quantity (having magnitude  as well as direction).           S.I. unit of Force is N (Newton).           Force can Change the State of Motion.                   Force can Change the Shape of an Object. s          Q.2. What is friction ?      Ans.2.  The force which opposes the motion of an object on the surface of another object is called force of friction. Force of friction is a contact force. The force of friction always opposes the applied force (direction of motion).

FRICTION Q.3.  Suppose your writing desk is tilted a little. A book kept on it starts sliding down. Show the direction of frictional force acting on it. Ans.3.                                 Q.4. What is the cause of friction? Ans.4.  Friction occurs due to the interlocking of irregularities between two surfaces in motion to each other. Every object has some sort of irregularities in its surface, so when two surfaces come in contact with each other and one object moves over the another, so their irregularities get interlocked and moving object starts losing its energy in breaking the interlocking and finally it comes to rest.                                             Q.5. What are the factors on which friction depends? Ans.5.  There are two factors affecting friction: 1.      Nature of the surfaces: Friction increases with roughness and decreases with smoothness of the surfaces. On rough surfaces, there are a larger number of irregularities than the s

PRACTICE WORKSHEET (CLASS - VIII) TOPIC – FORCE AND PRESSURE 1. When a force acts on a moving object, it can make the object a) move faster b) slow down c) stop d) all of these 2. Name the type of forces involved in the following :  a) A horse pulling a cart _________________________  b) A moving boat coming to rest when rowing is stopped ___________________ c) A coin falling to the ground on slipping from hand ______________________  d) A sticker attached to steel almirah without glue _________________________ 3. Two students fought over a lunch box, both started pulling it from opposite ends but the box didn't move from its place. What will you infer about the magnitude and direction of the forces? 4. An archer shoots an arrow in the air horizontally. However, after moving some distance, the arrow falls to the ground. Name the initial force that sets the arrow in motion. Explain why the arrow ultimately falls down. Assertion / Reason :  For question numbers 5, two sta
