Which statement reagarding the idealized model of motion called free fall is true?
A. A freely falling object has a constant acceleration called the acceleration due to gravity.
B. The idealized model of motion called free fall applies in cases where the distance of the fall is large compared with the radius of the astronomical body on which the fall occurs.
C. The effect of air resistance is factored into the equations of motion in the idealized model called free fall.
D. Free fall only models motion for objects that do not have an initial velocity in the upward direction.

  1. B. The idealized model of motion called free fall applies in cases where the distance of the fall is large compared with the radius of the astronomical body on which the fall occurs. FALSE
    C. The effect of air resistance is factored into the equations of motion in the idealized model called free fall. FALSE
    D. Free fall only models motion for objects that do not have an initial velocity in the upward direction. FALSE, IT IS FALLING WHILE STILL GOING UPWARD.
