Please explain if the product of uncertainities related to to the measurement of position and momentum of particle is independent or depends on velocity of particle.
Fredrik said:The uncertainties depend on the state.
If the particle has a velocity, i.e. if the state is such that there's a vector v such that a velocity measurement will certainly have the result v, then the momentum uncertainty is zero, no matter what v is.
It's "Heisenberg" by the way.

how it' s describe if we measure the position we can't find momentum
It's a theorem in quantum mechanics that tells us that if you perform a long series measurements of either position or momentum on identically prepared particles, then regardless of the preparation, you will get a wide range of results for either the position measurements or the momentum measurements. (The product of the widths of the ranges of measurement results will never be smaller than ħ/2). In other words, it tells us that there's no way to prepare a particle such that results of position measurements will be close to the average, and results of momentum measurements will be close to the average.sciboudy said:what i s uncertainty principle mean ?? what is it ?
The Heisenberg Uncertainty Principle is a fundamental concept in quantum mechanics that states it is impossible to know both the exact position and momentum of a particle at the same time. This means that the more accurately we know the position of a particle, the less accurately we can know its momentum, and vice versa.
It is called the "uncertainty" principle because it describes the inherent uncertainty in measuring both the position and momentum of a particle. This means that we can never have complete knowledge of a particle's state, and there will always be some level of uncertainty.
The Heisenberg Uncertainty Principle states that the more accurately we know the position of a particle, the less accurately we can know its momentum. This also means that the more accurately we know the position and momentum, the less accurately we can know its velocity. Therefore, the Heisenberg Uncertainty Principle is directly related to the uncertainty in measuring velocity.
Yes, the Heisenberg Uncertainty Principle is considered a physical limitation in our ability to measure certain properties of particles. This is due to the fact that the act of measuring one property of a particle can change its state, making it impossible to measure another property accurately at the same time.
The Heisenberg Uncertainty Principle challenges our traditional understanding of the physical world, as it shows that there are inherent uncertainties in the behavior of particles at the quantum level. This principle has led to the development of new theories and interpretations in quantum mechanics, and has greatly influenced our understanding of the fundamental nature of the universe.
