Conservation of Energy
... In an ideal situation this transfer of energy would be perfect and complete, but when was the last time you remember our universe being perfect…? This leads us to the second idea… 2. “In any energy conversion, there will always be some waste energy released as heat into the surrounding environment.” ...

Friction is the main cause of energy leaks in the system and the reason why mechanical energy is not fully conserved for a real roller coaster. This is because friction is a nonconservative force.
