Question

the drawing shows the cars of a roller coaster racing down the track. how does the law of conservation of energy best explain the energy of the cars on the track? the potential energy of the cars is being transformed into kinetic energy. the cars have potential energy, but no kinetic energy. the kinetic energy of the cars is being transformed into potential energy. the cars have kinetic energy, but no potential energy.

Explanation:

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed. As the roller - coaster cars go down the track, they lose height (decreasing potential energy) and gain speed (increasing kinetic energy). So, potential energy is transformed into kinetic energy.

Answer:

The potential energy of the cars is being transformed into kinetic energy.
