GCSE Physics Energy Stores and Wasted Energy - Insane Marble Run Calculations

This is a really cool video to explain how energy is wasted in the form of friction from a marble run.
The same of course applies to any downhill course and is the reason bob sled etc.. will all be done on Ice!
It is also I think my last at Trent College after 6 years of making videos, I am leaving so enjoy it!
