Meaning and Definition
The branch of physics that deals with the motion of bodies under the influence of forces, based on Newton's laws of motion.
A foundational framework in physics describing the deterministic motion of macroscopic objects, excluding relativistic and quantum effects. It encompasses kinematics, dynamics, statics, and the conservation laws of energy and momentum.

FAQ
Frequently Asked Questions
Yes, absolutely. It is perfectly accurate for describing the motion of everyday objects, vehicles, structures, and most astronomical phenomena. It forms the essential foundation for engineering disciplines.
Classical mechanics describes deterministic, continuous motion of macroscopic objects. Quantum mechanics describes probabilistic behaviour of particles at atomic and subatomic scales, where energy is quantised.
Sir Isaac Newton, who formulated its three fundamental laws of motion and the law of universal gravitation in the 17th century.
No, classical electromagnetism (described by Maxwell's equations) is a separate, though contemporaneous, pillar of classical physics. 'Classical mechanics' specifically concerns motion and forces.
The branch of physics that deals with the motion of bodies under the influence of forces, based on Newton's laws of motion.
Classical mechanics is usually academic, technical in register.
