Classical mechanics is a branch of physics that deals with the study of the motion of physical objects under the influence of forces. It was developed by scientists such as Isaac Newton and Galileo Galilei and forms the basis for much of our understanding of the physical world. Classical mechanics describes the motion of macroscopic objects at speeds much slower than the speed of light and is typically applied to everyday phenomena such as the motion of planets, balls thrown in the air, and the behavior of machines. The principles of classical mechanics are based on Newton's laws of motion, which describe how objects interact with each other and the forces acting upon them.
