Answer 2

Answer:

D)Friction is low

explanation

Complete step by step solution:

When we walk friction is observed between our feet and the ground and this friction helps from skidding off the surface and also helps to grip to the surface on which we walk. When we walk, we apply some energy for the movement of the body, but due to friction, some of the energy is wasted.

While walking, you apply a backward force on the surface on which you are standing as well as a downward force is exerted due to body weight.

The coefficient of friction is low and much less than one. A system with a low coefficient of friction has a low resistance to the surfaces sliding across one another.

The fact that ice has a very low coefficient of friction it is difficult to apply force; hence it makes it difficult to walk on the ice.
