Mechanics 2 "loop the loop"

... Mechanics 2 "loop the loop" Task What is the minimum release height needed to "loop the loop." Investigate and validate. To do this I will create a theoretical model to calculate the minimum height required for the roller coaster to just reach the top of the loop then look at the height required to fully complete a loop. I will validate my theoretical model using a track. Assumptions So I can make a relatively simple model I will have to make some assumptions: * There is no friction because if there was there would be some work done against it and would mean I could not use the conservation of energy. Roller coasters run on wheels against smooth metal which would not have much friction. * Air resistance is negligible as most roller coasters are designed quite aerodynamically and have a large mass which would not be affected by a significant amount. * No energy is lost e.g. sound
