Question

6. In which case will friction be more: a man walking on a street or a man walking on an ice slab?
Why?​

Answer 1

Answer:

A man walking on street have more friction,because he has better grip on street due to present of sand etc.

On the other hand, ice will have less friction because it is 1st form of solid (water) and water is slippery.

Rough surfaces have more friction as compared to smooth surfaces due to their rough hinges.
