Desktop level integrated device, complete quantitative verification, data recording, and image drawing of Newton's Second Law in 3 minutes. Specially designed for high school and university physics experiments and STEM maker spaces, tool free, zero programming, and ready to use. Typical experimental results (example): When the mass m is 0.200 kg and the load is 0.49 N, the measured acceleration is 2.42 m/s ², the theoretical value is 2.45 m/s ², and the relative error is less than 1.5%. Classic experimental mode: constant mass, variable force (hook code step loading). Constant force, variable mass (magnetic counterweight). Free exploration (student defined variables).
