Keep on Truckin' - Analyzing Motion
-----------------------------------

***Advance Organizer or Activity Extension/Enrichment***
Use "acceleramp" w. the following data table: KoT_data-table_v2-alt.doc


> Part 1: Determining Speed and Velocity

Set up ramp & runway on countertop along window-wall: ring stand + test
tube clamp (near "Fortress of Solitude"); use tape strips to mark the
following distances (in meters):  -1; 0 (bottom of ramp); 1;  2; 3; 4; 5.
Use meter sticks as "guard rails" along edge of counter; place books in
front of gas valves. Use three (3) textbooks for bumper slightly beyond 5m
mark. Place 100g mass in bed of green army truck; secure w. masking tape.

Need three (3) student timers for each of three (3) trials; record average
time for each trial.


> Part 2: Describing Acceleration

Need six (6) student timers for each of four (4) trials. Use Logger Pro to
emulate the following data table & graph (Page 1 only):

   KoT_Part2_v4a_analyzed.xmbl

Note: Page 2, y-axis shows cumulative times to reach thresholds, e.g., 0m 
mark, 1m mark, etc.

Post-lab discussion &/or P.O.D.s:

Q. Does the graph on Vernier graph, Page 1 actually show acceleration?
A. No! Explain.

Q. Problem(s) re: positive- & negative acceleration using formula:
   a = v(f) - v(i) / t
A. ?

p. 24, No. 4
Use the following graph to illustrate constant acceleration:
extras/p24-no4_acceleration-due-to-gravity.xmbl
(alternate method of solving problem)

Q. How fast was Bob driving BEFORE "the law" stopped him?
A. Exact speed cannot be determined, but we can assume it was 20 mph OVER 
the speed limit.
