we are able to walk on a hard surface easily as compared to smooth surface because of friction.
hope it helps!
we are able to walk on a rough surface as compared to smooth surface because of friction.........
because friction exerts a backward force on the surface so it is easy to walk .......
rough surface has pores on it......these pores rub against the frictional force acting on it........
I hope it will help you
