Scientific method
Read data, identify the system, choose the model, write relations with SI units, then check the order of magnitude.
Exam focus
Precise definitions, labelled diagrams, unit conversions, document analysis, and justified numerical results.
Forces and motion
Always state the reference frame, system, applied forces, and vector directions before calculating.
Units
Force in newtons (N), mass in kg, distance in m, speed in m/s.
