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

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

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

    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.

    In a computer simulation, Jeffrey moves a magnet (Magnet 2) toward another magnet (Magnet 1) that cannot move. What happens to the potential energy in the system of magnets?

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

    The potential energy increases because Magnet 2 moves against the magnetic force.

    The potential energy decreases because Magnet 2 moves against the magnetic force.

    The potential energy decreases because Magnet 2 moves in the same direction as the magnetic force.

    Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can move the carts one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?

    Moving the cart on Track 1 one space to the right (?).

    Moving the cart on Track 2 one space to the left (?).

    Moving the cart on Track 2 one space to the right (?).

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