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.
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.
Potential energy is used when going up hill on a roller coaster. When it starts gong down the potential energy is converted to kinetic energy.
When the roller coaster - or any object, for that matter - is at its highest point, it has more potential energy than when it is at a lower point.
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.
