Conservation of Mechanical Energy
BlackBoard Notes

======================= Photo - Click for a Larger Version =============================

======================= First Board Section =============================

• Is mechanical energy conserved for a ball in free fall?
• E = K + U_g
  • where K = ½mv² and U_g = mgy

======================= Second Board Section =============================

• Predictions are not graded
• Don't round energy calculations.
  • Keep same number of sig. figs. as in the data table
• If you click the wrong point when marking the ball's position, choose "Undo" immediately!

======================= Third Board Section =============================

• Note: The following may not be needed since the order of experiments has changed!
• Next two weeks:
  • Lab instructions will be printed for you and available in lab
