Can the % of Energy lost due to friction be negative? Or is it always positive?
The percentage of energy lost to friction is always positive, as confirmed in the discussion. A negative loss would imply an addition of energy, which contradicts the laws of thermodynamics. The concept of infinite motion machines that generate energy through friction is deemed impossible.
