    Study Notes

    Quantum Mechanics

    • Describes the behavior of matter and energy at the atomic and subatomic level.

    Limitations of Classical Physics

    • Not applicable to the field of atomic and subatomic physics.
    • Classical physics is not sufficient for describing nature at the atomic and subatomic scale.

    Approximations of Quantum Mechanics

    • At the macroscopic scale, classical mechanics can be derived as an approximation.

    Key Differences

    • Quantum mechanics differs from classical physics in its probabilistic nature, where the position and momentum of particles are uncertain.
    • In classical physics, the position and momentum of particles are precisely known.
