what energies and forces does a rollercoaster use
- Anonymous
Roller coasters use only a few different types of forces and energies. The most important is the first hill of the coaster. The reason you go so high up is so you can get lots of potential energy (which is a result of the force of gravity). As you go down the hill, the potiential energy changes into kinetic energy as you speed up, however some of the energy is absorbed by air resistance and the wheels turning. Since there is no other source of energy, the first hill is always the biggest.

Also, the speed of the roller coaster is limited by that first hill. The higher the hill, the faster you will go. You really can't make it go any faster once the ride has been built.
