Swimming is possible on account of

Options

A. First law of motion
B. Second law of motion
C. Third law of motion
D. Newton's law of gravitation

Answer

To solve the question "Swimming is possible on account of," we will analyze the principles of physics involved in swimming, particularly focusing on Newton's Laws of Motion.

### Step-by-Step Solution:

1. **Understanding the Forces in Swimming**:
- When a swimmer moves their arms and legs, they push the water backwards. This action involves applying a force on the water.

2. **Applying Newton's Third Law of Motion**:
- According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. This means that when the swimmer pushes the water backwards, the water exerts an equal and opposite force on the swimmer.

3. **Resulting Motion**:
- The reaction force from the water pushes the swimmer forward. This is how swimmers are able to propel themselves through the water.

4. **Conclusion**:
- Therefore, swimming is possible due to Newton's Third Law of Motion, which explains the interaction between the swimmer and the water.

### Final Answer:
Swimming is possible on account of Newton's Third Law of Motion.
