Question scenario: Let's say that we have a heavy bowling ball and roll it across a horizontal platform that can be vertically raised. Experimental condition #1: The bowling ball is not moving, and I raise the platform with X amount of force directly underneath the static ball to raise the ball 1-foot. Experimental condition #2: the bowling ball is given a forceful horizontal movement along the surface of the horizontal platform and, at mid-point of travel, I raise the platform directly underneath the ball to raise the ball 1-foot. Does condition #2 require more upward force than #1 ??? This is not a homework Q. Just curious. I assume the answer is yes.
