Question

D. In the following situations write whether friction will increase, decrease or not change 1 A meteor enters the Earth's atmosphere from space 2. Powder is sprinkled on carrom board 9. Area of contact between two objects increases 4. Roughness of one of the two surfaces in contact increases 5. A person tries to walk on marbles​

Answer 1

1. if a meteor comes to earth atmosphere the friction would increase which will cause the fire of meteor

2. if powder is sprinkled on a carrom board , the friction would decrease which will cause in smoothness of the board

3. if area of contact between two object is increased, the friction would increase

4. if roughness of one 9f the two object is increased, the friction would increase .

5. if a person tries to walk on marble, the friction would decrease causing the falling of the person .
