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.

Based on the magnetic field line diagrams, what will happen next with these two sets of magnets?

• The magnets in Set 1 will repel, and the magnets in Set 2 will attract.

• The magnets in Set 1 will attract, and the magnets in Set 2 will repel.

• The magnets in Set 1 will not move, and the magnets in Set 2 will attract.

• In both sets, the magnets will attract

An engineer is investigating potential energy with two identical magnetic roller coaster cars on different sides of a center magnet that cannot move. To test her ideas, the engineer will move one car one space. Which movement will result in the largest increase in potential energy?

• Moving Car 1 one space toward the center magnet.

• Moving Car 2 one space away from the center magnet.

• Moving Car 2 one space toward the center magnet.

• All these movements will result in the same change in potential energy because they each move a roller coaster car the same distance.

A spaceship is traveling through space. Suddenly, its speed increases. What can you say about the kinetic energy of the spaceship?

• The kinetic energy increases as its speed increases.

• The kinetic energy decreases as it is converted into speed.

• The kinetic energy remains the same because speed and kinetic energy are not related.

• There is no way to know what happens to the kinetic energy.

In a computer simulation, Juan 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 does not change because the magnets in the system do not change.

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

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

• The potential energy decreases because Magnet 1 moves in the same direction as the magnetic force.
