Question

in a computer simulation, jose moves a magnet (magnet 1) closer to another magnet (magnet 2) that cannot move. which statement accurately describes the change in potential energy? the potential energy decreases because magnet 1 moves in the same direction as the magnetic force. the potential energy does not change because the magnets in the system do not change. the potential energy decreases because magnet 1 moves against the magnetic force. the potential energy increases because magnet 1 moves against the magnetic force.

Explanation:

1. First, analyze the magnetic interaction: When moving a magnet closer to another, we need to consider the magnetic poles. If the poles are like (e.g., north - north or south - south), they repel each other.
2. Then, relate to force and potential energy: If Magnet 1 is moved closer to Magnet 2 and they repel (assuming like poles), the magnetic force on Magnet 1 is pushing it away. So when Jose moves Magnet 1 closer, he is moving it against the magnetic force.
3. Finally, recall the relationship between work, force, and potential energy: When an object moves against a conservative force (like magnetic force in this context), work is done on the object, and this work is stored as an increase in potential energy. So the potential energy of the system of magnets increases because Magnet 1 is moved against the magnetic force. The other options are incorrect: The first option says it moves in the same direction as the force (but if repelling, the force is opposite to the direction of moving closer), the second option is wrong as the configuration (distance between magnets) changes, and the third option incorrectly states the potential energy decreases when moving against the force.

Answer:

The potential energy increases because Magnet 1 moves against the magnetic force.
