In a follow-up class exercise, students create an Excel macro that What is the formula of uncertainty? The uncertainty principle is alternatively expressed in terms of a particle's momentum and position. The momentum of a particle is equal to the product of its mass times its velocity. Thus, the product of the uncertainties in the momentum and the position of a particle equals h/(4) or more. 4 5 5 : T F T ; @ 5 : U F U $ ; (5) where T T @ 5 ;/ is the mean value of the T values.
