Newton formulated the laws of motion and gravity from "summary" of To Explain the World by Steven Weinberg
In the seventeenth century, the English physicist Isaac Newton made a groundbreaking contribution to the field of physics by formulating the laws of motion and gravity. These laws laid the foundation for classical mechanics, revolutionizing our understanding of the physical world. Newton's first law of motion states that an object will remain at rest or in uniform motion unless acted upon by an external force. This law, also known as the law of inertia, explains the tendency of objects to maintain their state of motion. The second law of motion introduced by Newton quantifies the relationship between an object's mass, acceleration, and the force acting upon it. This law is expressed mathematically as F = ma, where F represents the force applied to an object, m is the mass of the object, and a is the acceleration produced. Newton's third law of motion states that for every action, there is an equal and opposite reaction. This law describes the reciprocal nature of forces in nature, emphasizin...
