    • Chapter 13 Section 3 Conservation of Energy
    • Friction
      • Friction is a force that opposes motion between two surfaces.
      • Careful Now!
    •  
    • Energy is Conserved in a Closed System!
      • A closed system is a group of objects that transfer energy only to each other.
      • The law of conservation of energy states that energy cannot be created or destroyed.
      • Energy efficiency is a comparison of the amount of energy used before and after a conversion.
      • An aerodynamic object has a shape that helps it be more energy efficient.
      • Formula One
      • How does friction, aerodynamics, and energy efficiency affect this?
