Question

{ CHAPTER - FRICTION /CLASS - 8} .A cell is rolled down an inclined plane first on a smooth table and then on a cloth piece
1. in which case is the distance covered by rolling cell more ?
2. why is the distance covered by cell different on different surface ?

Answer 1

Answer:

1. Distance is more in smooth table

Explanation:

2. Friction on smooth surface is much lesser than friction on cloth. So, cell experiences greater drag in cloth surface and hence, travels lesser distance

Answer 2

Answer:

$Hello$ $mate!$

1. The cell covers more distance in the first case, the smooth table.

2. This is because, the cloth offers more friction than the table. And friction always opposes the relative motion.
