Transcript

  • 1. Chapter 6 Work, Energy, Power
  • 2. Work
    • The work done by force is defined as the product of that force times the parallel distance over which it acts.
    • The unit of work is the newton-meter, called a joule (J)
  • 3. Energy
    • The amount of energy transferred to the object is equal to the work done.
    • Types of Energy
        • Kinetic Energy = “Motion Energy”
        • Potential Energy = “Stored Energy”
  • 4. Kinetic Energy
    • Kinetic Energy is the energy possessed by an object because it is in motion.
  • 5. Gravitational Potential Energy
    • Gravitational Potential Energy is the energy possessed by an object because of a gravitational interaction.
  • 6. Conservation of Energy
    • Energy can neither be created nor destroyed, but only transformed from one kind to another.
  • 7. Power
    • Power is the time rate of doing work.
  • 8. Power
    • The unit of power is a joule per second, called a Watt (W).
  • 9. On to problems...
  • 10.
