No, Sir Isaac Newton did not copy Charles-Augustin de Coulomb. Newton and Coulomb were two different physicists who lived in different time periods and made significant contributions to the field of physics in their respective eras.
Isaac Newton (1643-1727) was an English physicist and mathematician who formulated the laws of motion and universal gravitation. He published his seminal work, "Mathematical Principles of Natural Philosophy" (also known as the Principia) in 1687, which laid the foundation for classical mechanics and provided a framework for understanding the motion of objects under the influence of forces, including gravitational forces.
Charles-Augustin de Coulomb (1736-1806) was a French physicist who is best known for his pioneering work in electrostatics and magnetism. He formulated Coulomb's law, which describes the relationship between electric charges and the forces they exert on each other. Coulomb's law, published in 1785, quantitatively describes the electrostatic force between charged particles.
While both Newton and Coulomb made significant contributions to the field of physics, their work focused on different areas. Newton's laws of motion and gravity describe the motion of objects in the presence of gravitational forces, while Coulomb's law addresses the interaction between electric charges. These contributions were made independently and are distinct from each other.
It is worth noting that scientific progress often builds upon the work of earlier scientists, and ideas and discoveries can influence subsequent researchers. However, there is no evidence to suggest that Newton copied Coulomb or vice versa. Their respective contributions were the result of their own investigations and insights into the natural world.
