How does speed affect roller coaster?
The rate of change in velocity (the speed of an object in a certain direction) is known as acceleration. The force of gravity pulling a roller coaster down hill causes the roller coaster to go faster and faster, it is accelerating.
What is the force that affects the speed of the roller coaster?
Gravity applies a constant downward force on the cars. The coaster tracks serve to channel this force — they control the way the coaster cars fall. If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates.
How does the weight of the roller coaster affect the speed?
heavy objects will have a higher terminal velocity than light objects. It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.) Therefore, heavy objects will fall faster in air than light objects.

How do roller coasters confuse your body?
A roller-coaster can also cause negative G, pushing a passenger upwards out of the seat. The body gets confused by these fluctuations and produces adrenalin, which increases heart rate and blood pressure. The result – a primeval thrill.
Do heavier roller coasters go faster?
When the train is released at the top, the center of mass will be lower than for a uniform rider distribution. If my analysis is correct, then the fastest speed should be obtained by putting heavy riders toward the back, so that they are right on top of the hill when the hoisting mechanism lets go of the train.
What is the fastest roller?
Currently, the fastest roller coaster in the world—traveling at up to 149 miles per hour—is the Formula Rossa at Ferrari World Abu Dhabi in the United Arab Emirates. The world’s tallest, standing at 456 feet, is Kingda Ka at Six Flags Great Adventure in New Jersey.
