The force push is a force power that is catergorized as force telekietics. The force push is not as powefull as force wave but is more presise and controlable.

A force push is like a giant hand, the hand of the force if you will, picking up and moving the item around. Up, down, left or right, or throughing it for greater velosity. The fact that the movement can be in any direction has caused confusion in that its called force push. Some Jedi have taken to calling it force pull or 'force movement', this is perfectly fine, but unnessasery in most instanses.
