Air Table	String
Spark Timer	Carbon Paper
Pulley	Paper
Weight

Procedure:

1. Watch the video.
2. Print off the data sheet. | [disregard the + drawings on the sheet]

Observations and Data:

1. The mass on the scale is 200g.
2. The spark timer is set to 0.1 seconds.
3. Calculate the potential energy at the start:
   • 
   • In all calculations use "m" as being equal to only the mass that is falling; "h" is measured from the length of the data sheet (first measurable dot to the last measurable dot)
   • "g" is calculated from the data sheet - calculate the velocity of the object at the start of the data sheet (V_A) and at the end (V_B). Hint: You can measure the distance the object travells and you know the time between each dot.
4. Calculate the kinetic energy at the end Hint: v is actually V_B
5. Calculate the percent difference

Conclusion:

1. State the percent difference between E_k and E_p and provide reasons to support the difference.
2. What law was proved in this lab, and what does it state.
3. State any applications of the lab.
