Question
Why do we sometimes slip on smooth surfaces like ice or polished floors? Explain.
Show answer
Answer
Smooth surfaces have very little friction, so our feet cannot grip and we slip.
Explanation
- Friction between our feet and the floor lets us grip and walk safely.
- Ice and polished floors are very smooth, so the friction is very small.
- With too little friction to grip, our feet slide and we slip.
Too little friction on smooth surfaces makes us slip.
