Lin sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Lin can move the carts one space to the left or one space to the right. Which movement will increase the potential energy in the system the most?
answer choices
Moving the cart on Track 2 one space to the right (→).
Moving the cart on Track 2 one space to the left (←).
Moving the cart on Track 1 one space to the right (→).
All these movements will result in the same change in potential energy because they each move a magnetic cart the same distance.
