The Motion of Free Fall
BlackBoard Notes

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

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

• What is the acceleration of an object in free fall?

• The Sketch:

Time conversion: 40 dots = 1 sec Calculate y for each even numbered dot, as measured from dot zero!

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

• The Data Table:

• Pro tips:
  • Quickly fill column with '10.0' (see section I, step 2 of Excel instructions)
  • Start your graph after measuring the third point. Add each additional point to the graph as it is measured (see section III).

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

• The Graph (recall last week's Excel exercise!):

How does your measured acceleration (ao), compare with the expected acceleration (g = 980 cm/s2)?

======================= Fourth Board Section =============================

• Measured Acceleration: Class Results {leave room for the max number of groups in any section}

ao (cm/s2)
