During a roller coaster ride, the energy of motion brings the roller coaster to the top of a large hill. When it reaches the top, the roller coaster begins to roll downwards and an energy transformation occurs. What type of energy does the roller coaster have as it travels downhill?

Magnetic energy is created to keep the roller coaster from falling off the tracks.

The energy of motion is converted from the stored energy the roller coaster had at the top of the hill.

Chemical energy is created as the roller coaster travels down and causes a chemical reaction.

Thermal energy is converted as the wheels create friction against the tracks of the roller coaster the temperature begins to decrease.
