PART II: PE and KE At the lower center, turn the speed to “Slow”. At the left, drag the ruler to the KE/PE bar graph. Swing the pendulum so the total Energy Shows. Place ruler so that 5 cm is above the total energy bar. At this point the total should be 5
PART II: PE and KEAt the lower center, turn the speed to “Slow”. At the left, drag the ruler to the KE/PE bar graph. Swing the pendulum so the total Energy Shows. Place ruler so that 5 cm is above the total energy bar. At this point the total should be 55 cm - 5 cm = 50 cm. Remember to subtract that 5 cm each time you take a reading. (Note: this needs to be altered depending upon the...
