- Whenever a body moves or tends to move over the surface of another body, a force comes into play which acts parallel to the surface of contact and opposes the relative motion. This opposing force is called friction.
EXPLANATION:
- As we know that friction is a force that opposes motion.
- It's difficult to walk on ice because there's very no friction between the bottoms of your shoes and the ice. Therefore option 1 is correct.
- When your shoes push back on the ground the force of friction between the ground and your shoes pushes you in the opposite direction, propelling you forward.
- Ice has a very smooth surface, and it often has a thin layer of water on it. Since molecules in the liquid phase can move around freely hence, water acts as a lubricant to fill in the imperfections in the surface and further decrease friction.
