How do roller coasters go so fast?

Answer 1

Roller Coasters go fast because they use gravity to their advantage. Because the cars weigh a lot, they fall at very high speeds from high in the air. Some of the new roller coasters being built also are propelled forward using the force created by high powered magnets.

Answer 2

Roller Coasters go really fast because when your on them with other people there is a lot of weight on the roller coaster which make them go faster. Then roller coasters have wheels and your also going down hills some of the time.

Answer 3

Gravity. If you look hard at a coaster, the cars are moved by power to a high point, and released. After that, they are moved downhill by gravity. They coast- which is why they are roller coasters.

Answer 4

The weight of the train and gravity. Sometimes engineers use electromagnets in the track to get it to the right speed.

Answer 5

losen the friction but it will be dangerous so to make it safer add belts

Answer 6

beacause every year scietists develop better ways of speeding up rollar costers and because their are rollor costers for diffrent age groups

Answer 7

The potential energy imparted to the coaster in the initial rise from its start point and the conversion of that potential energy into kinetic energy.

Answer 8

Gravity. If you look hard at a coaster, the cars are moved by power to a high point, and released. After that, they are moved downhill by gravity.

Answer 9
