Which of the following option is correct regarding freely falling object?

Options

A. Initial velocity of object must be zero
B. Object is moving under the influence of gravity
C. Acceleration of object is zero
D. Both (1) & (2)

Answer

To solve the question regarding the characteristics of a freely falling object, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Freely Falling Objects**:
A freely falling object is one that is moving solely under the influence of gravity, with no other forces acting on it (like air resistance).

2. **Analyzing Option 1**:
- The statement is: "The initial velocity of the object must be 0."
- This is **not necessarily true**. A freely falling object can start from rest (initial velocity = 0) or it can have an initial velocity greater than 0. For example, if you drop a ball from a height, it starts with an initial velocity of 0. However, if you throw it downwards, it has a non-zero initial velocity. Thus, this option is **incorrect**.

3. **Analyzing Option 2**:
- The statement is: "The object is moving under the influence of gravity."
- This is **true**. By definition, a freely falling object is one that is only influenced by gravitational force. Therefore, this option is **correct**.

4. **Analyzing Option 3**:
- The statement is: "Acceleration of the object is 0."
- This is **incorrect**. The acceleration of a freely falling object is equal to the acceleration due to gravity (g), which is approximately 9.81 m/s² (or 10 m/s² for simplification). Therefore, this option is **incorrect**.

5. **Analyzing Option 4**:
- The statement is: "Both 1 and 2."
- Since option 1 is incorrect and option 2 is correct, this option is also **incorrect**.

### Conclusion:
The correct option regarding freely falling objects is **Option 2**: "The object is moving under the influence of gravity."
