Stored Energy Changes II Quick Check 1 of 51 of 5 Items 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 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. 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. 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. 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. Skip to navigation

Answer 1

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.
