Question

1. olivia 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?

a the potential energy increases because the train moves against the magnetic force
b the potential energy decreases because the train moves against the magnetic force
c the potential energy decreases because the train moves in the same direction as the magnetic force
d the potential energy does not change because the magnets in the system do not change

Explanation:

When an object moves against a force (in this case, the magnetic force), work is done on the object. This work is stored as potential energy in the system. So, if the train moves against the magnetic force, the potential energy of the system of magnets increases.

Answer:

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