Earth's path around the sun is call what?
Orbit

What law is observed, according to Newton, if you let an untied balloon go?
Law 3, Because if the balloon is facing one way, the air will push it that way, causing an action reaction force.

How can Newton's laws be used to explain how rockets are launched into space?
When a rocket is being released, you can tell air is being released from under it causing it to go up. In law 3, it is explained that for every action, there is an equal and opposite reaction. Like how the rockets air is being released under, and the rocket go's up.
