What is the focus of Newton's Laws?

The focus of Newton's Laws is indeed the foundation of classical mechanics. These laws form the core principles that describe the motion of objects and how forces influence that motion. Specifically, Newton's first law addresses the concept of inertia, the second law provides a relationship between force, mass, and acceleration, and the third law explains the principle of action and reaction. Together, they establish the mathematical and conceptual groundwork for understanding not only how objects move but also how they interact with each other in a wide range of physical scenarios. This foundational framework is crucial for studying and applying principles in various fields, including engineering, physics, and even certain areas of biological sciences when considering biomechanics.
