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)
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.
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 is at its peak when the magnets are
first released, then it decreases steadily. Energy
stored in the magnetic field becomes zero.
The velocity and kinetic energy of the system
increase as the energy stored in the magnetic field
increases.
