Classical mechanics is the branch of physics that deals with the motion of macroscopic objects and systems under the influence of forces. It was developed by scientists such as Isaac Newton and Galileo Galilei in the 17th and 18th centuries.
Classical mechanics is based on three fundamental principles:
1. Newton's laws of motion - which describe how the motion of an object changes in response to the forces acting on it.
2. The principle of conservation of energy - which states that energy cannot be created or destroyed, only transformed from one form to another.
3. The principle of conservation of momentum - which states that the total momentum of a system of objects is conserved in the absence of external forces.
Classical mechanics is used to study a wide range of phenomena, from the motion of planets and stars to the behavior of fluids and solids. It provides a framework for understanding the behavior of everyday objects, such as cars and bicycles, as well as more complex systems, such as machines and structures.
