Classical Mechanics

Definition

Classical mechanics is a branch of physics that deals with the motion of macroscopic objects, such as planets, projectiles, and everyday objects, under the influence of forces. It is the foundation for understanding the physical world around us and forms the basis for many other areas of physics.
