The ramp in the railway station has rough surface .why?

Answers

Answer:

To increase the friction so we do not slip while walking.

Explanation:

If the surface is smooth then the frictional force between the ramp and the feet becomes less and the chances of slipping are greater.

The ramp on a railway station has a rough surface to increase friction so that we do not slip while walking on it. If the surface is smooth, then the frictional force between the ramp and the feet becomes less and the chances of slipping are greater.
