Can the Percentage of Energy Lost to Friction Be Negative?

Click For Summary
SUMMARY

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.

PREREQUISITES
  • Understanding of basic thermodynamics principles
  • Familiarity with the laws of energy conservation
  • Knowledge of friction and its effects on mechanical systems
  • Basic physics concepts related to motion and energy transfer
NEXT STEPS
  • Research the laws of thermodynamics in detail
  • Explore the concept of energy conservation in mechanical systems
  • Study the effects of friction on energy loss in various materials
  • Investigate the feasibility of perpetual motion machines and their implications
USEFUL FOR

Students of physics, engineers, and anyone interested in understanding energy dynamics and the implications of friction in mechanical systems.

Can the % of Energy lost due to friction be negative? Or is it always positive?

It is always positive. A negative loss is an addition and if that were the case, we would all have infinite motion machines that produce energy via friction. A nice idea, but impossible.
