Build circuits from a battery, bulb, resistor, switch and meters. Current, voltage and power are computed with Ohm's and Kirchhoff's laws.
Three experiments: inertia, the ΣF = ma relation and interaction forces. Motion is computed from equations and measured with instrument precision, so the error analysis is real. Interface in three languages.
A cart moves along the track by x = x₀ + v₀t + ½at² — horizontal track, inclined plane or pulley. A sensor records measurements, the acceleration is found in two ways, the error is computed and a PDF report is generated. Teachers assign it to groups.
Teachers create a group and share an invitation code; students join with it. Labs are assigned with a deadline and score, results are graded automatically, and reports and independent work are exchanged as PDF.
