A roller-coaster would go faster with more people in it because with moer people the better the ride alsothe people that are ridding will give the roller-coaster potential energy. A roller-coaster would go slower with an empty car will give the roller-coaster kinetic energy than with peolpe in it.
Miller Lite
A roller coaster increases kinetic energy when it is going downhill, as gravity is pulling it down and accelerating it. The potential energy is converted into kinetic energy as the roller coaster gains speed.
When the roller coaster is at its highest position and is not moving then its potential energy is highest
When the roller coaster is at its highest position and is not moving then its potential energy is highest
The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path.
No, the roller coaster is not the only example of a closed energy system.
80% of the people screaming on roller coasters are doing it because it just comes out (don't be afraid to let it out) and it makes the ride fun. And I'm guessing that you are afraid of roller coasters but to answer your question it does, it gets all the butterflies away as you go down that first drop. My first roller coaster i remember that weird feeling in my stomach and once i started screaming it went away fast. try laughing too, but screaming works best (at least with me)
The potential energy is highest at the top of the first hill or peak of the roller coaster because it is at its maximum height above the ground. As the roller coaster descends, potential energy is converted into kinetic energy as the car gains speed.
The model uses less energy than the real one does.
It depends on the roller coaster's height,speed,and location. :p
Energy is transferred from potential to kinetic on a roller coaster as the coaster descends from a higher elevation to a lower elevation. As the coaster moves downwards, gravitational potential energy is converted into kinetic energy. This energy transfer allows the coaster to gain speed and momentum.
