can a roller coaster have the same amount of kinetic energy and potential energy at the same time?

Answer 1

A roller coaster can have the same amount of kinetic energy and potential energy at certain points during its ride. This occurs at the highest point of the ride when the coaster is momentarily at rest before it starts to descend. At this point, all of the coaster's potential energy has been converted into kinetic energy. As the coaster descends, its potential energy decreases while its kinetic energy increases.
