Lab Reports for APPB @ FHS

Labs for AP Physics B

General Info
Each graph should be neat and reasonably large (they should approach half the size of a page).

Always double-space your lab write-up. If possible, type it. Presentation is important (it's part of your grade).

APPB Lab 1---Quantitative and Qualitative Descriptions of Motion. A report on the Blinky Buggy (constant velocity model) and cart on a ramp (constant acceleration).

Use a computer and a motion detector to collect pos-t, vel-t, and accel-t graphs of a “blinky buggy” on a level surface and a PASCO cart on an incline. Write about the graphs using the lab rubric as a guide. You should provide accurate representations of the motion of each situation in three modes: graphical, verbal, and algebraical (the rubric does not explicitly mention this, but I just did--). This is all the written instruction you will get, but I will do my best to answer all reasonable questions. Be sure to talk intelligently and "wholistically" about the purpose of the lab and what you learned. This lab should include these graphs:

position-time (both CV & CA models)
velocity time (both CV & CA models)
Optional: x vs. t "linearized" (CA model only)
Optional: v vs. x "linearized" (CA model only)

Think about what the graphs illustrate and write intelligently about what each aspect (shape of the
curve, slope, area, etc.) of the graph shows you. This lab report is due (in a composition notebook) by Tues., 9/3

APPB Lab 2---Free-Fall: The Acceleration due to the Earth's Gravitational Pull

Your group (no more than four people) should choose one of the methods below. Your goal should be getting data in one class period. Report writing should be carried out on your own time.

Free-Fall using the Digital Timer PDF

Determining g on an incline PDF

Questions to ask yourself: Why 3 trials for each case? Why sine of the angle? How do you calc. sine? Do I have any questions about the rubric? This lab report is due on Monday, 9/23.
