Why is it generally more difficult to walk without slipping on ice compared to walking on regular pavement?

Explanation

Walking on ice is difficult because ice has a much lower coefficient of friction than typical pavement, meaning there is far less resistance between a shoe sole and the icy surface to prevent sliding. This reduced friction is partly due to a very thin layer of liquid water that often forms on the surface of ice, acting almost like a lubricant. This is why techniques like walking with shorter, flatter steps, or using footwear specifically designed with additional traction, can help improve grip on icy surfaces.
