Classical Mechanics
The branch of physics that describes how macroscopic objects move under the action of forces is classical mechanics, founded on Newton's three laws of motion.
Overview
It models physical reality as particles and rigid bodies whose trajectories are fully determined by their initial conditions, expressed through differential equations and the conservation of energy and momentum.
Why it matters
For more than two centuries it served as the fundamental framework of physical science, and it transformed engineering, astronomy, and navigation before quantum and relativistic physics revealed its limits at the smallest and fastest scales.
