An engineer is investigating potential energy with two
identical magnetic roller coaster cars on different sides of a
center magnet that cannot move. To test her ideas, the
engineer will move one car one space. Which movement will
result in the largest increase in potential energy?
A.
Moving Car 1 one space toward the center magnet.
B.
Moving Car 2 one space toward the center magnet.
C.
Moving Car 2 one space away from the center magnet.
D.
All these movements will result in the same change in potential energy
because they each move a roller coaster car the same distance.
