Task: Story Composition
Input (English): Background Paragraph: It is often easy to think of the change in energy as a mountain or an inverted cone, depending on the situation. Imagine a positive point charge, with the corresponding electric field around it. If you are moving another positive point charge, the situation is like a mountain, with the original point charge at the peak. As the second charge moves towards the first, it must go up the mountain. This requires work, and increases the potential energy of the system. If, however, the second charge is a negative point charge, the two charges attract each other and the situation is like a cone the second charge easily falls towards the first, decreasing the potential energy. It would then require work to get the second charge up and out of the cone, away from the first charge.
Output (English): Adam is playing with some magnets which have a positive and negative pole. He tries to push them together but cant seem to do it. when he flips one of the magnets around that actually snap together very quickly.
