    Why has moving a mass up an incline suddenly required less energy then moving it across flat ground?

    Somebody better let Newton know.


    This thread is getting a bit .... strained.

    which is a shame, because I'd rather see more slug pictures.

    Um, I hate to ask this but I never quite understood for sure what a “slug” was. I am guessing it is:
    Slug - A bunch of batteries sitting on a bunch of traction motors.
    Calf – Fancy marketing term for slug?
    Thanks

    To answer my own question and for those who were also wondering I was 1/3rd right.
    Thanks to wikipedia:
    A slug does not have batteries. Most have weight in the form of concrete. Some carry fule for the Mother.
    Cow and Calf - My impression is they were identical too each other, (except for the lack of a cab in the calf), including use of a prime mover.

    A Roots blower is a spcific type of compressor who inards look like two figure 8 shaped rotors that are 90 degrees out of synch. As the rotors spin the compressor air. They can be powered by an exhaust powered turbine (it's then call a turbo charger) or directly off of the engine drive shaft (it's then called a supercharger). However, most turbo chargers uses a centifical compressor.
