Question

Walking become difficult when the ground is slippery . Why?

Answer 1

On slippery surfaces, the friction is comparatively less than on other surfaces. So, as the friction between your shoes/sandals and the floor is quite low, your footwear does not get enough grip on the floor and you can slip.

Answer 2

Hey Friend !

Friction depends on the roughness of the surface.

When the surface is rough , friction is more.
When the surface is smooth , friction is less.

It is easier for us to walk when the ground is not slippery , as friction is more.
Its difficult to walk on a slippery ground , as the surface is very smooth and friction is less.
