Roller Coaster RestrictionsAt no time can the track be more than 75 feet above the ground or go below ground level. No ascent or descent can be steeper than 80 degrees from the horizontal.

This places some limits on the design. For example, the coaster car can't go through a loop or over a hill that is taller than the initial hill because going higher would require more energy than it has available. If the track is too long, friction might eventually cause the coaster car to come to a complete stop.
TMNT Shellraiser at 121.5 degreesIt tops the list by dropping a mere half of a degree more than the coasters that follow it. To make the ride even more interesting, its cars hang over the edge of its 141-foot tower for 14 seconds before diving into the overbanked drop.
The minds behind the Kingda Ka at Six Flags Great Adventure in Jackson, New Jersey clearly understood this, as they combined speed and height to create the scariest roller coaster in the world.
Roller coasters almost always begin with an initial vertical drop. A motor hauls the cars to the top of a high hill and from that point on gravity is doing all the work. Typical vertical drops might range in height from 50 - 80 meters.
The first hill of a roller coaster is always the highest point of the roller coaster because friction and drag immediately begin robbing the car of energy. At the top of the first hill, a car's energy is almost entirely gravitational potential energy (because its velocity is zero or almost zero).
Mass does not make a roller coaster go faster but it does make it harder to slow down. This is why amusement parks test roller coasters with dummies filled with water. The water dummies increase the mass of the train making it harder for the resistance forces to slow it down so it's less likely to get stuck.
There's the nervousness while you wait in line, the excitement as you buckle yourself in and the thrill as come speeding down that first drop. But as you age, you may be wondering if it's even still safe to ride a roller coaster. The short answer is, probably yes.
Most coasters don't have a posted weight limit but if they do, that would be listed on the sign where the height restrictions are when you get in line. It's more common to see weight limits on water rides like water slides, and some kiddie rides where parents ride with kids. I hope this helps!
Formula Rossa — Ferrari World, United Arab EmiratesThe Formula Rossa roller coaster is the mother of speed machines for coaster enthusiasts. The hydraulic launch coaster was built in 2010 and is the fastest coaster in the world, reaching a speed of 149 mph at its fastest point.
