What happens if a roller coaster is too fast?
If a coaster's acceleration is too great, however, the force of gravity stops the flow of blood to the eyes and brain. At higher levels for longer periods, extreme g-forces could cause blackouts or temporary blindness. But the g-forces roller coasters exert are relatively harmless.
What park has the scariest roller coasters?
The two scariest roller coasters in the US are Kingda Ka at Six Flags Great Adventure and Top Thrill Dragster at Cedar Point. Unlike other ride compilations, such as the 12 longest coasters, this list is somewhat subjective.
Why are roller coasters teardrop shaped?
Rollercoaster loops are most often not perfect circles – instead, they are teardrop-like in shape. This is because it takes a greater amount of acceleration to get the train around a perfectly circular loop.

How do most roller coasters end?
Different types of brakes are used to stop the train at the end of a ride. These brakes use friction to slow down and stop a roller coaster's momentum by converting the train's kinetic energy into heat energy. For example, roller coasters are kind of like riding your bike down a hill.
