Examples of this regarding rollercoasters is Kinetic energy from the gravitational pull.

As the rollercoaster goes higher into the air there is an increase in potential energy.

However once the rollercoaster starts to go downhill that potential energy is all turned into Kinetic energy due to the gravitational pull.

Due to this, the rollercoaster is able to continue along the track at a high speed without slowing down too much. Techniques used on a rollercoaster track to create potential energy are loops and hills.
