I have a rocket for my player. It isn’t affected by gravity and rotates when pressing left and right arrows, and moves forward (with a motor block) when pressing up. When the rocket collides with something that is also moving, it starts rotating all on its own. The only way to sort of stop it is to hold down the arrow key that is the opposite direction its rotating in.

You have rotation enabled, most likely. Turn it off and all your problems will be solved.

Wrong again. You can rotate objects without turning on rotation. Rotation makes it able to freely rotate, as in get rotated by other objects.
