In the absence of friction or wind resistance, a body that is in motion will never stop moving and have a constant velocity. This is in accordance with Newton's first law of motion, which states that an object in motion will remain in motion at a constant velocity unless acted upon by an external force.
If there is no friction (or wind resistance) a body that is in motion will ...
eventually begin to turn and change its direction
never stop moving and have a constant velocity
eventually convert all of its kinetic energy into heat energy
stop after a while with a changing velocity
