It's called gravity, it attract the sun toward the gravitational pull making everything circulate. I don't really know how to explain it though.
Its option 3 an object has potential energy
Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star
One, three and five are correct.
Although if the second statement is saying that stars use gravitational force to support nuclear fusion which in turn produces energy then that would be correct, but I don’t think so :)
