They want to go up but gravity holds them down.

Well yes on the balance things on Earth want to go up or down.

Newton's First Law is "Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." That means that any objects at rest wants to stay at rest, and moving objects want to keep on moving.
On Earth, however, gravity keeps this from happening. If you remove the Earth and put a ball in space, it won't move. If you push it, it'll move forever. On the earth, gravity holds these things down, so the ball would stop rolling mainly because of friction.

A very vague question.
Thing can mean anything. And by up or down, do you mean go upward from the ground toward space? or up/down a hill until it reaches something flat?
things heavier then the substance they are located in (air, water, whatever) tend to move downwards until they encounter something. Then if friction with the object is not enough to stop them, they roll/slide down teh object until they reach a place where friction does stop them.
Things lighter then the substance they are located in does the same, but upwards.
That MIGHT answer this question, but it is pretty vague.

It depends on your age. When you're young, your thing wants to go up, all the time. As you get older, your thing is more and more likely to go down.
