- It is difficult to walk on an oily floor because friction is very less on an oily floor. Necessary friction to walk is absent on this surface.
- On rough surfaces, there are a larger number of irregularities. So the force of friction is greater if a rough surface is involved.
- Here we have a smooth surface, irregularities are filled up by oil which decreases the force of friction.

Difficulty in Walking on an Oily Floor
Walking on an oily floor can be quite challenging due to several factors. However, the correct answer to why it is difficult to walk on an oily floor is option 'D' - the force of friction is very less. Let's delve into the details to understand why this is the case:
Friction and its Role in Walking
Friction is the force that opposes the relative motion between two surfaces in contact. It plays a crucial role in walking as it provides the necessary traction or grip between our feet and the ground. When we walk, our feet exert a force on the ground, and the ground exerts an equal and opposite force on our feet due to the friction between them. This force allows us to push against the ground and move forward.
Effect of Oil on Friction
When an oily substance is spilled on the floor, it creates a layer between the surface and our feet. This layer of oil acts as a lubricant, reducing the friction between our feet and the floor. Consequently, the force of friction is significantly decreased, making it difficult to walk on the oily surface. Here's why:
1. Reduced Coefficient of Friction: The coefficient of friction is a measure of the amount of friction between two surfaces. In the case of an oily floor, the coefficient of friction is greatly reduced due to the presence of the lubricating oil. This reduction in the coefficient of friction makes it harder to generate the necessary force to propel ourselves forward while walking.
2. Decreased Traction: Traction refers to the grip or adhesion between two surfaces. When an oily substance is present on the floor, it reduces the traction between our shoes and the floor. As a result, our feet tend to slip or slide on the oily surface instead of firmly gripping it. This lack of traction makes it challenging to maintain balance and stability while walking.
3. Increased Instability: Walking on an oily floor increases the chances of losing balance and falling. The reduced friction and traction make it easier for our feet to slip, leading to instability and potential accidents. This is particularly true when we need to change directions or make sudden movements, as the reduced friction makes it harder to control our body's motion.
Conclusion
To sum up, walking on an oily floor is difficult primarily because the force of friction is very less. The presence of oil reduces the coefficient of friction, decreases traction, and increases instability, making it challenging to walk with ease. It is important to exercise caution and take necessary steps to clean or avoid such surfaces to prevent accidents and ensure safety.
