Explain how the principle of energy conservation is applied in designing a roller coaster to ensure it completes its course.

• By ensuring the roller coaster has enough initial kinetic energy to reach the end.

• By designing the roller coaster to have its highest point at the beginning, converting potential energy into kinetic energy to move through the course.

• By using motors to continuously add energy to the system.

• By making the track as flat as possible to avoid energy transformations.
