QUICK QUESTION about uncertainty principle:

First:
If subatomic particles have momentum, then don't objects at rest have momentum [since they are made of these momentous particles] ?

My main question is:
If the position of an electron is uncertain, then isn't the position of an object NOT constant? Even to the slightest degree?

Thanks, I'm working on a little something having to do with time and velocity, and came upon space and this quick question came up.

Yes, the momentum of particles that make up an object are taken into account via temperature.

The position of an object is constant to a certain degree. It just depends on how accurate you want to get. An individual electron in an orbital is constantly in motion and has a random chance of being in a specific location at any moment in time.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
