    Study Notes

    Bernoulli's Principle

    • The Bernoulli's principle is associated with the concept that the pressure of a fluid decreases as its velocity increases.
    • A constant quantity along a streamline in a steady flow is the sum of the potential head, kinetic energy, and pressure energy per unit weight.

    Heisenberg Uncertainty Principle

    • The Heisenberg uncertainty principle states that it is impossible to know both the exact position and momentum of a particle at the same time.
    • The Heisenberg uncertainty principle relates to wave-particle duality, which suggests that particles can exhibit both wave-like and particle-like behavior.
    • The Heisenberg uncertainty principle has implications for quantum mechanics, specifically in the measurement of subatomic particles.
    • There is a trade-off in the measurement of particle position and momentum, such that increasing the precision of one will necessarily decrease the precision of the other.
    • The Heisenberg uncertainty principle also affects the measurement of energy and time, as increasing the precision of one will decrease the precision of the other.
    • The Heisenberg uncertainty principle challenges classical physics by introducing an inherent uncertainty in measurement, contradicting the deterministic nature of classical mechanics.
