Homework Help: Circular motion

  1. Sep 9, 2008 #1
    in circular motion, on a track, which is exactly a quarter of a circle, starting at 180 degrees(9 0 clock) and ending at 270(6 o clock) what is the direction of the total force working on an object dropped from the start at 180? no external forces, friction etc... is it always with the direction of motion or does it differ at different angles??

    Hi devanlevin,

    You mentioned some forces that are not acting, but what forces are there that are acting on the object?
