    This is an experiment showing violation of Newton's First Law of Motion with the invention of the low voltage heavy armature rail gun converted to a linear motor with the arrest of the heavy armature/bullet.
    This follows from the experiment done on 27May2022, presented in the youtube link
    https://www.youtube.com/watch?v=rYihBZmBbRI
    where we showed how the centre of gravity moved forward by about 30cm and upwards by about 3mm.
    In that experiment, the bow of the system did not move forward, while the centre of gravity did. While scientifically and in practice the system did move forward and upwards too, thereby violating the inertia condition with internal force, for popular
    appeal this show - the bow going backward by 4cm instead of forward by any amount - is perhaps not spectacular.
    Another issue was the recoil as a result of the rolling friction. The quickly accelerating heavy armature/bullet pushed the rails back a good deal, much as a runner on dusty earth kicks back the dust. Had the friction been less (more sliding involved)
    then the effective length of the barrel would have increased, and there would be more efficiency involved in the motor's performance (it would go further and higher) with a single hit. In the abovementioned experiment, the system went back 24 cm, thus
    the effective barrel length was 65-24=41cm only.
    To improve the efficiency, thus, a commercially available conductive grease was placed on the rails. I thought this grease would make the backward reaction from rolling friction less, and that would increase the efficiency of the railgun motor. However,
    this addition of the grease between the rails and the brass cylinder would increase the circuit's resistance, thus decreasing the current, and with that, the force upon the cylinder.
    The manufacturer claimed that this grease would prevent sparking. I was under the impression that the avoidance of sparking, causing welds that had to be broken, would lead to the armature moving faster, thus increasing the efficiency.
    It was quite an experience to see the experiment in action! After an oopsy situation, the armature progressed up the rails in a comparatively slow pace, as expected from the lower current.
    A 1.1V drop meant that 1.1V*2000F=2200 coulombs were discharged in 1.9 seconds, the time of the armature on the rails. The average current through the armature was thus 2200C/1.9s=1158Amps.
    There was a lot of sparking, caused probably by the current through certain constituents of the grease. This sparking did not cause welds as is usual with the much more conducting copper and aluminum foil contact done usually. It would appear, that the
    grease did its purpose, and let the roller slide over the rails more than grip it.
    What is remarkable is the low level of recoil in this situation where grease has been placed on the rails. The system went back by only 4cm. This way, the effective barrel length was 65-4=61 cm.
    Because of this higher efficiency, and despite the much lower current, the motor with grease on the rails performed better. The centre of gravity went forward by 35.5cm and upwards by 4mm.
    Most visibly, the whole system moved forward at the bow end by 1.5cm. This visually proves that inertia has been violated.
    Evidently, with a different system that provides both metallic and sliding contact (for lower circuit resistance and near-full barrel length respectively) the railgun motor would perform a lot better.
    However, implementing that would require resources beyond the means of your humble and impoverished, retired old engineer; thoroughly marginalized, so working entirely by himself.
    Nevertheless, it was possible for me to construct a much bigger gun, while using the same capacitor power pack. The experiments with that gun will be shown in subsequent videos.
