I don’t have access to your class’s specific Student Guide unless you upload it or paste the text. I can, however, recreate the data table and a short student guide for the experiment using the equipment you listed.
Quick question: what is the experiment title or goal? (e.g., measure acceleration of a toy car pulled by hanging washers / Atwood-style setup, measure friction, etc.) If you’re not sure, I’ll assume it’s the common toy-car + pulley experiment where hanging washers provide the driving mass.
Below is a ready-to-use data-table template and brief instructions assuming that experiment. I can adjust it if your guide has different variables.
Suggested data table (columns — use three repeats per condition)
- Trial #
- # of washers (n)
- Mass of washers (m_h) (g and kg)
- Mass of car + accessories (m_c) (g and kg)
- Total system mass (m_total = m_c + m_h) (kg)
- Distance traveled (s) (m)
- Time 1 (t1) (s)
- Time 2 (t2) (s)
- Time 3 (t3) (s)
- Average time (t_avg) (s)
- Experimental acceleration a_exp = 2s / t_avg^2 (m/s^2)
- Theoretical acceleration a_theory = (m_h * g) / (m_c + m_h) (m/s^2) (use g = 9.81 m/s^2)
- Percent difference = 100 * |a_exp - a_theory| / a_theory
- Notes / issues (e.g., slipping, pulley friction, tape)
Short procedure notes
- Measure masses: use the mass balance to find m_c (car plus any tape/paperclip used) and the mass of one washer; multiply to get m_h for n washers.
- Setup: place track level (or at the intended angle), run string over pulley, attach washers to the hanging end and car to the other. Mark the start and finish points on the track to get s (use metric tape).
- Runs: pull car to starting mark, release from rest, start stopwatch when released, stop when car reaches finish. Record three times per washer count.
- Compute a_exp using a = 2s/t^2 (starting from rest). Compute a_theory with the formula above. Repeat for a range of washer counts.
- Safety: secure pulley and track, ensure string won’t slip, use duct tape or paper clip only as needed.
Uncertainty & tips
- Repeat at least 3 times and average.
- Use longer distances if possible to reduce relative timing error.
- Account for pulley friction and string mass qualitatively; if you want, I can add a correction method.
- If track is inclined, theoretical formula changes — tell me the angle if relevant.
If you want, I can:
- Produce this as a printable table (CSV or paste-ready).
- Add example rows with numbers.
- Recreate the exact Student Guide format if you paste a copy or describe its required fields.
