An electric drive for a motor vehicle comprises a first gear stage, driveable by the electric motor, a second gear stage, driveable by the first gear stage, and a differential drive, driveable by the second gear stage. Highly and accurate and consistent delivery of the object facilitates single and multi-player use for training, such as in the sport of soccer. The processor is connected to a system memory that contains a page table with multiple levels. MOI are tagged with magnetic particles and moved with a magnetic field through a fluid, or zones, of higher specific gravity that prevents, by flotation counterforce, unwanted less dense materials from entering. Preferred polyurethane products are thermoplastic polyurethanes. In this manner, information on the specification is obtained.
