Lesson
Distance is the actual path length travelled, while displacement is the shortest directed change in position. Speed uses distance per time, while velocity uses displacement per time with direction.
Learning objectives
Explain Distance, Displacement, Speed, and Velocity using the correct Grade 9 Physics terms.
Connect observation, graph, ray, or calculation to the underlying principle.
Use units, labelled features, and the final physical meaning accurately.
