Squishy Circuits. ImageQuiz: The Electromagetic Spectrum. BC Hydro - Energy in BC. Energyinsports.png (1509×2176) Conservation of energy of a rollercoaster using high speed video. Summary High speed video of a roller coaster allows students to perform careful analysis of a familiar situation.
Students use high speed video to determine whether a roller coaster is an example of a system in which mechanical energy is conserved. Students use frame counting to measure the speed of a roller coaster as it heads up a hill, and then measure the speed as the roller coaster comes back down the hill. The outcome of the measurements depends on which part of the roller coaster they measure because a motor continues to propel the roller coaster until it begins to climb the hill.
