also important to note that the Plancks constant and momentum units are a bit odd, but they always work themselves out by cancelling, especially when we solve for indeterminacy in position. may be worth practicing working through the units and looking at how they cancel out, because this becomes really convoluted sometimes and we can lose points on a test for errors in units.
It helps me to memorize the units of Planck's constant/J (kgm^2^s^2) since I know that anything I enter into the equation from there will either have to be of these units or converted to them so I can cancel out. So mass would be in kg and velocity would be in m/s.
