It is easier to roll a body over a surface than to slide it on the same surface. Due to this _____is greater than rolling friction.

Options

A. Sliding friction
B. Static friction
C. fluid friction
D. kinetic friction

Answer

To solve the question, we need to understand the types of friction involved when a body is rolled versus when it is slid over a surface.

### Step-by-Step Solution:

1. **Understanding Friction Types**:
- There are three main types of friction: static friction, sliding (or kinetic) friction, and rolling friction.
- Static friction acts on a body at rest, sliding friction acts on a body in motion that is sliding over a surface, and rolling friction acts on a body that is rolling over a surface.

2. **Comparison of Friction Types**:
- When a body is rolled (like a wheel), it experiences rolling friction.
- When the same body is slid across the surface, it experiences sliding friction.

3. **Observation of Forces**:
- It is commonly observed that rolling a body requires less force compared to sliding it. This is because rolling friction is generally less than sliding friction.
- Therefore, we can denote the force required to overcome rolling friction as \( F_{rolling} \) and the force required to overcome sliding friction as \( F_{sliding} \).

4. **Conclusion**:
- Since it is easier to roll a body than to slide it, we can conclude that sliding friction is greater than rolling friction.
- Therefore, the answer to the question is: **sliding friction** is greater than rolling friction.

### Final Answer:
Due to this, **sliding friction** is greater than rolling friction.
