    Dylan puts two magnetic toy trains very close to each other on a track. What will happen next, and why?

    The trains will not move because the magnets are not touching.

    The trains will move closer to each other because the magnetic force will pull the trains together.

    The trains will move away from each other because the magnetic force will push the trains apart.

    The trains will move away from each other because the magnets are not touching.

    Dakota moves a magnetic toy train toward a magnet that cannot move. What happens to the potential energy in the system of magnets during the movement?

    The potential energy increases because the train moves against the magnetic force.

    The potential energy decreases because the train moves against the magnetic force.

    The potential energy decreases because the train moves in the same direction as the magnetic force.

    The potential energy does not change because the magnets in the system do not change.

    Pablo sets identical magnetic carts on two tracks. At the end of each track is a large magnet that cannot move. Pablo 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?

    Moving the cart on Track 1 one space to the right

    Moving the cart on Track 1 one space to the left

    Moving the cart on Track 2 one space to the left

    All these movements will result in the same change in potential energy because they each move a cart the same distance.
