When an item has been launched into orbit, what happens?
1: It continues to fall but its path never reaches the ground.
2: Centripetal force from Earth's gravity keeps it from being accelerated toward Earth.
3: It no longer falls because the weakness of Earth's gravity with increased height has made it lighter than air.
4: It no longer falls because it is outside the atmosphere.
5: It is kept in orbit by attraction to the sun and moon.
