Mechanics is a fundamental branch of physics that deals with the motion of objects and the forces that cause such motion. It forms the basis for understanding many other areas of physics and engineering. At its core, mechanics is divided into two main subfields: classical mechanics and quantum mechanics.

Classical mechanics, developed primarily by Isaac Newton, describes the motion of macroscopic objects, from falling apples to orbiting planets, using concepts like displacement, velocity, acceleration, force, and energy. Key principles include Newton's laws of motion and the law of universal gravitation. This framework is remarkably accurate for everyday speeds and sizes.

Quantum mechanics, on the other hand, emerged in the early 20th century to explain the behavior of matter and energy at the atomic and subatomic levels. It introduces concepts such as quantization of energy, wave-particle duality, and probability, which differ significantly from the deterministic nature of classical mechanics.

Within classical mechanics, further distinctions are made. Kinematics focuses solely on the description of motion without considering the forces involved, while dynamics analyzes the relationship between forces and motion. Statics deals with objects at rest or in equilibrium, where the net force and torque are zero. The study of mechanics is essential for fields like aerospace, civil engineering, robotics, and astrophysics.
