Question

In absence of friction

• A. our shoes will remain intact
• B. we will not be able to walk
• C. we will be able to slide smoothly

Answer 1

The correct option is D all the above will happen

Friction force always opposes relative motion between contact surfaces.

which results, we see wear and tear in machine parts or shoes.

But in absence of it, we will not be able to walk, our shoes will remain intact and we will be able to slide smoothly.

Hence Option D.
