According to Newton's laws of motion, what is the first principle regarding forces?

• A. For every action, there is an equal but opposite reaction.
• B. One body exerts force on another.
• C. Objects in motion stay in motion.
• D. Force equals mass times acceleration.

Answer: (B)

The first principle regarding forces as stated in Newton's laws of motion is something that emphasizes the interaction between two bodies and the concept of force. This principle, which reflects the idea that one body can exert a force on another, lays the groundwork for understanding how forces operate in various physical scenarios. Newton's laws fundamentally describe how objects interact with one another and how their movements are affected by applied forces. While the concept of action and reaction, the relationship between motion and inertia, and the relationship between force, mass, and acceleration are crucial principles in their own right, they are extensions or specific instances derived from the foundational idea that forces are interactions between different bodies. Therefore, understanding that one body exerts force on another paves the way for comprehending the more complex dynamics of motion and forces, which are encapsulated in the other laws. It highlights the relational aspect that is critical to the study of mechanics.
