What is a "retarding force"? I've seen this in a couple of past year papers and was not sure what they meant. They mostly asked it like :" Find the retarding force... "
  • A retarding force is a force that is opposing the motion of the object.
    A good example would be friction force.

What does effective resistance mean ?
  • Effective resistance is also called total resistance.
    But be careful since a question can ask for the effective resistance (total resistance) of just a parallel section of an entire big circuit. The you calculate just for that parallel.
