It is more difficult to walk on a sandy road than on a concrete road because
sand is soft and concreter is hard
the friction between sand and feet is less than that between concrete and feet
the friction between sand and feet is more than that between concrete and feet
the sand is grainy but concrete is smooth

I think in sandy road we did not fall I think due to more friction between sand and feet it is difficult to walk because sand has more contact forces upon feet so it is difficult to walk.

Friction is responsible to hold the object in its place firmly. As there is more friction between concrete and feet it is more easy to walk on concrete than on muddy road. Hope its clear.

Friction is required for walking, and friction between foot and sand is less than that of walking on concrete road so that it is easy to wake on concrete road than on sand.

Aishu said:   1 decade ago
Since concrete road is more leveled than that of sand, the contact area is more with the feet so that friction will be more. So can walk easily on concrete.

Option C is correct.

Because if there is more friction then it is more difficult to walk than in concrete.

C is correct answer as in sand we have more contact area and more friction as compare to concrete road.

Answer Should be "C".

Because Friction is more in the case of the sandy road than the concrete road.

Neeharika said:   9 years ago
I think option c is correct because friction is more when we walk on sand than on the conrete road.

Sultan said:   5 years ago
I think there is less normal force so that our feet immersed in sand and we feel difficult.

Budhdeo said:   8 years ago
I think option C is right since friction stands for the opposition offer in a walk.
