Explain how potential energy converts to kinetic energy in the loop-the-loop section of the rollercoaster. Make sure to note when the potential energy of the coaster is at its lowest in the loop-the-loop and when the kinetic energy of the coaster is at its highest. (Refer to the above diagram as needed)

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.
