How Roller Coasters Work
By Taylor Brady
Energy of Roller Coasters
Roller Coasters have Kinetic Energy, Potential Energy, and Mechanical Energy. The potential energy happens when the cart is about to fall. So just when you are about to fall, the coaster has potential energy. The coaster gains kinetic energy when it falls. The whole coaster (besides going up the first hill) is not by chain or machine, it's just gravity pulling it. If the energy did not change than the roller coaster would either stay still or, keep on going for ever.
Wooden and Steel
Wooden roller coasters usually don't go as high or as fast as steel roller coasters. They also don't loop most of the time. However, wooden coasters do sway unlike steel roller. Steel coasters can have more loops and sharp turns because they are more grounded and stable
