Per NCERT, why is it DIFFICULT to walk on a WET or POLISHED FLOOR (or on ice)?
ABecause Newton's laws don't apply on water
BBecause friction is reduced — your foot slips back when pushing, so there's less forward reaction force from the ground
CBecause air resistance increases
DBecause gravity is weaker on wet floors
Answer & Solution
Correct answer: B. Because friction is reduced — your foot slips back when pushing, so there's less forward reaction force from the ground
Per NCERT §6.6 'Bridging Science and Society' box, low friction = poor reaction force from ground = slipping. The other options misstate.
