... We see from equation (1) that if the resultant force on a particle is zero during an interval of time, then its linear momentum L must remain constant. Since equation (1) is a vector quantity, we can have situations in which only some components of the resultant force are zero. For instance, in Cart ...

If you consider two different observables whose operators do not commute, then a system cannot be in a definite state for both of those observables ...
