LOOK AT THE IMAGE:

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.

LOOK AT THE IMAGE:

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.

LOOK AT THE IMAGE:

Bryce moves a magnetic toy train away from a magnet that cannot move. What happens to the potential energy in the system of magnets during the movement.

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

• The potential energy decreases because the train moves against (away) the magnetic force.

• The potential energy increases because the train moves against (away) the magnetic force.

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