If two opposite pole of magnets are put with a 2m distance between them, and a car travels at 5m/s right between the two poles, Does its speed our direction change?

I haven't totally understood your answer. To be more simple, would the ball "Which is tied to a rope and the other end of the rope is tied to a pole" projected at 20 m/s Maintain its speed in vacuum **assuming No friction exists, Only gravity exists** The tension in the rope.

I was wondering what might happen If we for instant, Rotated a ball around an axis in a vacuum chamber. First, If the initial speed was 20m/s would it remain like that forever, hypotheticaly saying No friction exists and that Air Resistance does not exist as the Ball rotates in vacuum. Also...
