Please put a full explanation! The kinetic energy of the attracted magnet and iron rod came from potential energy in the system,
Evidence Card B: Magnet and Iron Rod
In the Sim, I observed that the amount of potential
energy changed as I moved an iron rod away from a
magnet. When the rod and magnet were released, they
moved toward each other.
How did potential energy get stored in the
magnet/iron rod system?

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

i think that is the right

a is the correct answer
