<u>Answer:</u>

The following are the things we can learn about energy in roller coaster.

  • All roller coasters work using the principle of gravitational energy.
  • All roller coaster utilise the Potential energy.
  • Roller coasters convert the potential energy into kinetic energy.
  • Friction is reduced in roller coasters as it decreases the speed of roller  coaster.

Roller coasters do not have engines whereas Gravity pulls them and potential energy gets converted into kinetic energy providing its motion. Due to the friction and air resistance, the energy gets reduced as the ride proceeds.
