In brief, the main difference between quantum and classical physics is the difference between a ramp and a staircase. In classical mechanics, events (in general) are continuous, which is to say they move in smooth, orderly and predicable patterns. Projectile motion is a good example of classical mechanics.

Classical Mechanics for Macroscopic Objects

Classical mechanics describes the motion of macroscopic objects such as spacecraft, planets, stars, and galaxies. The classical mechanics (as known as Newtonian mechanics) provides extremely accurate results as long as the domain of study is restricted to large objects and the speeds involved do not approach the speed of light. The classical theories are simple, but this branch of mechanics cannot be applied to extremely small particles moving at very high speed, as the results may turn inaccurate.

Quantum Mechanics for Micro (and macro) scopic Objects

Quantum Mechanics has much more complicated theories than classical mechanics (thanks to Einstein), but provides accurate results for particles of even very small sizes. Quantum Mechanics handles the wave-particle duality of atoms and molecules. Special theory of relativity by Einstein (1905) deals with particles of extremely small sizes while General theory of relativity by Einstein (1916) can be used to study all particles in general, ie. even particles of macroscopic sizes. Thus it can be said that General theory of relativity is a super set of Special theory of relativity. But still Classical Mechanics is preferred to General theory of relativity for particles of macroscopic sizes, just because of its simplicity.
