Question

Why is it more difficult to walk properly on a well-polished floor ?

Answer 1

It is difficult to walk properly on a well polished floor because it makes the floor smooth, lessening the friction in turn.

Friction is a phenomenon which resists motion when an object is rubbed against another.

So when the floor isa well polished , the person walking on the floor is unable to get the required grip, losing balance in the process .
