Question
Use the graph to answer the question. Two magnets are held apart. Once released, the south pole of one magnet moves toward the north pole of another magnet until the magnets collide. How does the graph reflect the changes in energy that occur? (1 point) Responses Kinetic energy is at its peak when the magnets are first released, then it decreases steadily. Energy stored in the magnetic field becomes zero. Kinetic energy is at its peak when the magnets are first released, then it decreases steadily. Energy stored in the magnetic field becomes zero. Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases. Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases. The velocity and kinetic energy of the system increase as the energy stored in the magnetic field increases. The velocity and kinetic energy of the system increase as the energy stored in the magnetic field increases. The kinetic energy of the system is derived from the thermal energy created by increased velocity. Energy stored in the magnetic field does not change.

To describe the energy changes occurring in the system of the two magnets, we need to consider the interactions between the magnetic field and the kinetic energy of the magnets.
When the magnets are held apart, they possess potential energy due to their magnetic fields. Upon release, the south pole of one magnet moves toward the north pole of the other magnet. As they begin to move closer together, the potential energy stored in the magnetic field is converted into kinetic energy as the magnets accelerate toward each other.
Based on the description, the correct interpretation of the energy changes in the graph would be:
**Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.**
This response captures the idea that initial potential energy is transformed into kinetic energy as the magnets come together, resulting in an increase in their velocity and kinetic energy, while the energy stored in the magnetic field decreases as a result of this conversion.
