Action and reaction forces act on

Options

A. Same body
B. Different bodies
C. Horizontal surface
D. Nothing can be said

Answer

To solve the question regarding action and reaction forces, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Newton's Third Law of Motion**:
- Newton's third law states that for every action, there is an equal and opposite reaction. This means that forces always come in pairs.

**Hint**: Remember that action and reaction forces are always equal in magnitude and opposite in direction.

2. **Identifying the Bodies Involved**:
- When one body exerts a force on another, the first body is considered to be applying the action force, while the second body exerts the reaction force back on the first.

**Hint**: Identify the two bodies involved in the interaction to understand where the action and reaction forces are applied.

3. **Analyzing the Action and Reaction Forces**:
- If body A exerts a force on body B, then body B exerts a force on body A. This means that action and reaction forces act on different bodies.

**Hint**: Use the example of walking: when you push against the ground (action), the ground pushes back against you (reaction).

4. **Conclusion**:
- Since action and reaction forces act on different bodies, the correct answer to the question is that they act on different bodies.

**Hint**: Always remember that action and reaction forces do not cancel each other out because they act on different objects.

### Final Answer:
Action and reaction forces act on different bodies.
