(1 point) Responses Kinetic energy transfers to potential energy, then some potential energy transfers to kinetic energy. Kinetic energy transfers to potential energy, then some potential energy transfers to kinetic energy. Kinetic energy transfers to potential energy, then some potential transfers to thermal energy. Kinetic energy transfers to potential energy, then some potential transfers to thermal energy. Potential energy transfers to kinetic energy, then some kinetic energy transfers to potential energy. Potential energy transfers to kinetic energy, then some kinetic energy transfers to potential energy. Thermal energy transfers to potential energy, then some potential energy transfers to thermal energy.

Answer 1

The correct description of the energy transformation for a model roller coaster rolling from point X to point Y is:

Kinetic energy transfers to potential energy, then some potential energy transfers to kinetic energy.

In this scenario, as the roller coaster ascends from point X to a higher point, kinetic energy is converted into potential energy. When it descends, potential energy is converted back into kinetic energy. Throughout the process, some energy may be lost as thermal energy due to friction, but the primary transformations are between kinetic and potential energy.
