At which point on the roller coaster will the car have the greatest amount of kinetic energy? Explain why.

• W because it is at the highest point and the GE is ready to be converted into KE.

• X because the gravitational energy will have all been converted into KE at the lowest point.

• Z because that is the end of the Roller Coaster.

• Y because the coaster is moving off the ground again.
