Which of the following figures represents uniform motion of a moving object correctly ?

Options

A.
B.
C.
D.

Explanation

To determine which figure represents the uniform motion of a moving object, we need to analyze each option based on the concept of uniform motion. Uniform motion occurs when an object moves with a constant velocity, meaning it covers equal distances in equal intervals of time.

### Step-by-Step Solution:

1. **Understand Uniform Motion**:
- Uniform motion means that the object travels equal distances in equal time intervals. This implies that the velocity is constant.

2. **Analyze the Graphs**:
- We have four options (graphs) to evaluate. We need to look for a graph that shows a straight line (indicating constant speed) or a horizontal line (indicating no movement).

3. **Evaluate Option 1**:
- Option 1 is a distance vs. time graph. If the graph is a straight line, it indicates that the distance is changing at a constant rate with respect to time. Therefore, this option represents uniform motion.

4. **Evaluate Option 2**:
- Option 2 shows a curve in the distance vs. time graph. A curve indicates that the distance is changing at varying rates, meaning the velocity is not constant. Therefore, this option does not represent uniform motion.

5. **Evaluate Option 3**:
- Option 3 also shows a curve in the distance vs. time graph, similar to option 2. This indicates that the velocity is changing, so this option does not represent uniform motion either.

6. **Evaluate Option 4**:
- Option 4 shows a horizontal line in the distance vs. time graph. A horizontal line indicates that the distance remains constant over time, which means the object is not moving (velocity = 0). While this is a form of uniform motion (constant speed of 0), it is still considered uniform motion.

7. **Conclusion**:
- The graphs that represent uniform motion are Option 1 (constant velocity) and Option 4 (constant speed of 0). Therefore, both options 1 and 4 represent uniform motion.

### Final Answer:
- **Option 1 and Option 4 represent uniform motion of a moving object correctly.**
