Use of the fisher price motor ALONE

[Some Guy]

ok, i have a demand for an output rpm of 4800, and I was wondering if the fisher price motor would be good enough with gear reduction down to this speed. Is torque higher if i use the fisher price motor alone, or is it with the gearbox. As you can see, the rest of my team members (3 of 'em) and I are rookies. I don't even understand what mNm means. If higher mNm means more torque, than the motor alone has higher torque? Also, how do the units progress for torque (what comes after/before mNm) and i would also appreciate if someone could link me to a site with basic electricity facts, about watts, amps, atc., since i don't know what those terms mean in real life. I'm really sorry if i'm asking a lot, but any and all help is greatly appreciated. Thank you, on behalf of team 1514.
