Do we need this equation

[Jonathan Liu 2I]

I am still confused as to what the equation is trying to prove or say

[Paul Zhang 2F]

What equation are you talking about? All the ones you need to know are in the Constants and Equations sheet on Lavelle's Chem 14A site: https://lavelle.chem.ucla.edu/wp-content/supporting-files/Chem14A/constants_equations.pdf.

I'm assuming you are referring to Heisenberg's Indeterminacy equation, and for that the answer is yes, we do need to understand what it means. But it is on the equation sheet so there is no need to memorize it. Just remember that if you want the uncertainty in velocity you need to convert delta p (momentum) into delta v (velocity) times m (mass).

Which equation?

I'm assuming that it's the Heisenberg Indeterminacy (Uncertainty) Equation. If you're not too sure about it, the Achieve textbook has a section that goes over that equation (Topic 1B.3 The Uncertainty Principle).

The heisenberg indeterminacy equation is used to make predictions about where an electron is based off on initial conditions. The more accurate one can determine the velocity the less accurate we know the position of the electron and vice versa.
