Imagine you are making an animation of a roller coaster with a pie chart representing the total amount of potential and kinetic energy in the system. What are the cars doing as the section representing kinetic energy increases in size? *

Assuming this roller coaster has zero change in total energy, the cars are descending and speeding up when they gain kinetic energy.

Aand b antarctica is a north pole.  field lines enter earth near the north pole.the magnetic pole near antarctica is a north pole.compasses point toward a magnetic pole that is a north pole.field lines circle earth from east to west.a compass can lead a hiker to the geographic north pole.
