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. This activity follows on the activity Measuring velocity of objects using video clips. Learning Goals A single frame from a video taken at 210 frames per second. The activity is intended to give students experience extracting data from video clips, and use physics concepts and reasoning to make conclusions about the situation.
