Answer 1

If you don’t have any other force (planets, stars etc..) and you don’t have air, you’ll travel at that same speed in the same direction… forever.

however, space is not empty, and there are particles that will slow you down (very slowly) and any planet/rock/star system/anything you find will alter your speed/course etc…
