In roller coaster terminology, what does "drop angle" refer to?

The term "drop angle" specifically pertains to the steepness of a hill or drop on a roller coaster. This measurement is crucial in determining the intensity and thrill factor of the ride. A steeper drop angle typically results in a more exhilarating experience for riders, as it can influence how fast the train accelerates down the slope due to gravity. Knowing the drop angle helps enthusiasts understand the design and engineering behind the coaster, as different angles can create various sensations, such as weightlessness or increased g-force. This aspect significantly contributes to the overall enjoyment and adrenaline rush that roller coasters are known for.
