### Realistic Values

How does one determine whether or not values calculated for uncertainty of velocity or position are realistic? How does one know they are realistic?

### Re: Realistic Values

The uncertainty for something very small like an electron should be relatively large because its so small its much harder to be certain about its position or momentum. The uncertainty of something like a ball or a car would be smaller because those are more easily seen and measured.
