This question already has an answer here:

What are the limits of the Force?

In geometrical terms how far can the force act? As i have only watched the movies, there is ambiguities in it.. For eg. Leia can feel the force then why she didn't when Luke was dying in the cold in the initial part of The Empire Strikes Back?

And in other terms like can it only be used for communication, and moving things or it has more to it?
