Which specific topic is covered in version of the lab— spring calibration or density ?
Depending on the specific textbook edition or workbook you are using, in the 7th-grade physics curriculum by A.V. Peryshkin typically covers one of two topics: Spring Calibration (Dynamometer) or Determining Density .
Dynamometer with a covered scale, a set of 100g weights, and a stand. Key Solved Elements:
Mark the pointer's position at rest (0 N), then add weights one by one (102g ≈is approximately equal to 1 N) and mark 1N, 2N, etc..
