Motion, Forces and Energy Lecture 7: Potential Energy & Conservation
... Energy losses (non-conservative forces) Kinetic friction is an example of a non-conservative force. When a book slides across a surface which is not frictionless, it will eventually stop. But all the KE of the book is NOT transferred to internal energy of the book. We can find the speed of the mass ...
