- 1Describing Motion: Scalars, Vectors and MeasurementThe vocabulary and the measurement habits the rest of the course runs on — SI units, significant figures, and the difference between a distance and a displacement.11 questions
- 2Uniform Motion and Motion GraphsConstant-velocity motion, and how to pull velocity out of the slope of a position-time graph and displacement out of the area under a velocity-time graph.Interactive10 questions
- 3Acceleration and the Kinematic EquationsWhat acceleration really measures, why a negative one does not always mean slowing down, and how to pick the right equation out of the four on your formula sheet.Interactive10 questions
- 4Free Fall and Motion in Two DimensionsGravity as a constant acceleration of downward, then adding displacements and velocities that point in different directions.10 questions
- 5Analysing Motion Data from an ExperimentTurning a column of raw position and time readings into a number you can defend — interval velocities, a line of best fit, a slope with its units, and an honest account of the error.10 questions
