physics question about energy conversion in a space without vaccuum&gravity???(like outer space?)?

Based on principle of conservation of energy, it is known that energy can only be converted, not destroyed. In a vacuum without gravity, will a moving mass move forever? i mean its like the kinetic energy of the moving mass cant be converted into heat/sound energy, so does that mean that the moving mass will forever have kinetic energy?

    If you don't take into account the gravitational pull of nearby planets, any drag due to gases or externallity, then yes that object will always have kinetic energy.
