Heisenberg's Uncertainty Equation

[Sofia Cerpa 2E]

what determines the indeterminacy of momentum and position? and in the equation, why is h over 4pi?

[Desiree Eshraghi 3A]

To answer your first question, momentum and position kinda work against each other. The more accurate you are in finding one, the less you are in finding the other.

The indeterminacy of momentum is affected by the indeterminacy of its components. This can either be the indeterminacy of velocity multiplied by mass, or the indeterminacy of mass multiplied by velocity (usually velocity is the factor that holds indeterminacy). The indeterminacy of position is based on the range of values that the position can be. For example, a particle that is +/- 5 meters from point A has an indeterminacy of 10 meters. Usually, they will give you the values for indeterminacy in an equation. As for the second question, I do not know, but I hope this helps!

The indeterminacy of momentum has to do with the uncertainty of the speed and mass of the particle. The more accurate you get measuring momentum, the less accurate you will get when measuring position and vice versa. As for your second question, I believe that the value h/4pi is a constant that was found using Schrodinger's equation and was then confirmed experimentally.
