Roughly - Classical mechanics deals with quantities on a macroscopic scale and quantum mechanics deals with quantities on a sub atomic scale.

Classical mechanics use the idea that a particle is at a particular place at a given time and thus uses the concept of a trajectory. Quantum mechanics deals only with probabilities of where a partilce will be found, the momentum and energy it will have etc.
