Your 'flow experiment' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
** Your initial message (if any): **
This is the resubmission of my acceleration data per your request.
** Is flow rate increasing, decreasing, etc.? **
** Is the velocity of the water surface increasing, decreasing, etc.? **
** How would the velocity of the water surface, the velocity of the exiting water, the diameter of the cylinder and the diameter of the hole be interrelated? **
** Explain how we know that a change in velocity implies the action of a force: **
** Does the depth seem to be changing at a regular rate, at a faster and faster rate, or at a slower and slower rate **
** What do you think a graph of depth vs. time would look like? **
** Does the horizontal distance (the distance to the right, ignoring the up and down distance) traveled by the stream increase or decrease as time goes on? **
** Does this distance change at an increasing, decreasing or steady rate? **
** What do you think a graph of this horizontal distance vs. time would look like? **
** The contents of TIMER program as you submitted them: **
** The vertical positions of the large marks as you reported them, relative to the center of the outflow hole **
** Your table for depth (in cm) vs clock time (in seconds) **
** Is the depth changing at a regular rate, at a faster and faster rate, or at a slower and slower rate? **

** According to the evidence here, is acceleration increasing, decreasing, staying the same or is in not possible to tell? **
I can't trace this back to your original data, so I'm going to have to ask you to insert this information into a copy of your original report. Please mark any revisions to the original with &&&&. I don't see an explanation here of how you obtained your accelerations; be sure that is included.
