Energy conversion from potential energy (the energy of position or composition) to kinetic energy (the energy of motion) is illustrated by the diagram of a roller coaster. When the coaster is in position A, the potential energy is _ and the kinetic energy is _. As the coaster moves to position B, the potential energy is _ and the kinetic energy is _ . As momentum carries the coaster into position C, the potential energy is _ and the kinetic energy is _ . Finally as the coaster reaches position D, the potential energy is _ and the kinetic energy is _.
the answer choices are: (and yes some are meant to be there twice)
at its highest value
at its lowest value
at its maximum value
at its lowest value
decreased to 1/4 of its maximum value
decreased to half the original value
increased to 3/4 of the original value
increased to half its maximum value
zero
