Question

what is difference between classical and quantum mechanics

Answer 1

In classical mechanics we try to observe universe more like rigid things we have many things constant like we have masses constant and we don't deal with non inertial frames. Its more likely dealing with bigger things pulleys, wheels but quantum mechanics is dealing with particle physics Thier Motion and dynamics which is somewhat similar to classical physics and which has many things explained what classical physics cant

Answer 2

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 predictable patterns. Projectile motion is a good example of classical mechanics.
