  1. Energy Pie Charts

  2. The Toy Car Lab Constant Velocity Motion

  3. Example 2 Toy Car Lab 1 2 3 Is the system isolated? Yes, there are no external forces! System = System = Toy Car, Table, Earth System = Toy Car System = Toy Car, Table Since the system is isolated, energy is conserved. 3 2 1

  4. The Ball Rolling Down an Incline Lab Uniformly Accelerated Motion

  5. Example 2 Ball Rolling Down an Incline System = System = Ball System = Ball, Incline, Earth System = Ball, Incline 1 Friction = No Friction = ? 2 3 Is the system isolated? 4 Yes, there are no external forces!

  6. Example 2 Ball Rolling Down an Incline System = Ball System = System = Ball, Earth, Incline System = Ball, Earth 1 Friction = No Friction = ? 2 3 Since the system is isolated, energy is conserved. 4 4 3 1 2

  7. The Pendulum Lab

  8. Example 3 The Pendulum Lab 1 5 How can we tell from the diagram if energy is dissipated? 2 4 Position 5 is lower than position 1! 3 System = System = Pendulum Bob, String, Clamp System = Pendulum Bob System = Pendulum Bob, String, Clamp, Earth System = Pendulum Bob, String

  9. Example 3 The Pendulum Lab 1 5 Is the system isolated? Yes, there are no external forces! 2 4 3 Since the system is isolated, energy is conserved. System = Pendulum Bob, String, Clamp, Earth 4 3 5 1 2

  10. Example 3 The Pendulum Lab 1 5 2 4 3 System = Pendulum Bob, String, Clamp, Earth 4 3 5 1 2
