F/m and PE gravitational

Some students tried to find acceleration by dividing Fnet by meters traveled instead of mass. This despite a few labs on the subject.

Many of you didn't even bother with Fnet and chose whatever force popped into your mind first either Mg or Frope. Only a few found the sum of Frope + -Mg

Most of you also decided that even though the elevator rose, it lost PE.
