how
In a model roller coaster, when it starts from point X and moves towards point Y, it begins with kinetic energy, as it is moving and has velocity. As the roller coaster climbs up towards point Y, some of this kinetic energy is transformed into potential energy, which is stored due to its increased height.
At the highest point, when the roller coaster is at its maximum potential energy, it starts descending towards point Y. As it moves downward, some of the potential energy is converted back into kinetic energy, as the roller coaster gains speed.
Therefore, the energy transformation in the roller coaster involves the transfer of kinetic energy to potential energy as it climbs up, and the transfer of potential energy back into kinetic energy as it comes back down.
The correct answer is:
Kinetic energy transfers to potential energy, then some potential energy transfers to kinetic energy.
