The diagram illustrates a section of a rollercoaster ride, with the car shown at several positions. The car moves without power from position X to position Y and then climbs the hill on the opposite side. What happens to the energy in the kinetic store and the gravitational potential store of the car as it travels from position X to position Y?
- Akinetic store: decreases; gravitational potential store: decreases
- Bkinetic store: decreases; gravitational potential store: increases
- Ckinetic store: increases; gravitational potential store: decreases
- Dkinetic store: increases; gravitational potential store: increases
